if (s == *(p+j)){
printf("ID number is in the array at position %d", j);
}else{
printf("Error: ID number does not exist.");
}
}
return 0;
Explanation:
The C program source code inputs integer values to dynamic array size, and the search variable is looked for in the array using a for loop. If the search term exists, then the index position is printed on the screen, else an error message is displayed on the screen.
Input a number and find the square root only if the number entered is greater than or equal to zero.
number = float(input("Enter a number: "))
if number >= 0:

how do hardware and software work together to allow a user to perform a function?
jointly, independently, repeatedly or separately?
Answer:
jointly
Explanation:
Because Hardware and Soft ware have to JOIN together to make something work
I hope i helped!
Hardware and software collaborate to enable a user to perform a function. The physical components of a computer system, such as the central processing unit (CPU) and memory, are referred to as hardware.
What is CPU?CPU is an abbreviation for Central Processing Unit, which is the main component of a computer system that is in charge of executing instructions and processing data.
The CPU is often referred to as the computer's "brain" because it performs the majority of the calculations.
When a computer user performs a function, the software sends instructions to the hardware, which then executes the instructions and performs the function.
When a user types on a keyboard to create a document, for example, the keyboard sends signals to the CPU, which processes the input and sends the output to the software application to display on the screen.
Thus, in this way, hardware and software are interdependent and work together to enable a user to perform a variety of functions on a computer system.

a bus is full of passengers. if you count them by either twos, threes, or fives, there is one left. if you count them by seven there will be none left. find the least number of passengers in the bus?
Answer:
91
Explanation:
You know that the number must end in 6 or 1 to get a left over of 1 when divided by 5. Six won't work because 2 divides evenly into a number ending into 6.
So the number ends in 1.
21 doesn't work because 3 divides into 21 evenly.
31 doesn't work because 7 does not divide into it.
41 doesn't work. 41 is prime. 7 won't divide into it.
51 is divisible by 3
61 seven does not evenly divide into 61.
71 seven leaves a remainder of 1
81 7 leaves a remainder.

b) Machine cycle defines a loop process with four major components. Explain why machine cycle is important? If the components of machine cycle are inter-swapped, would that cause any problems?Can we add another module to rectify the problem caused by inter-swapping?
Answer:
Machine cycle defines a loop process with four major components is explained below in detailed explanation.
Explanation:
The machine cycle has four methods i.e. fetch method, decoding method, execute method, and store method. All these methods are essential for the preparation performance of the processor. By the machine cycle, the execution of the processor can be measured and the device can be decided.
Importance of Machine Cycle
The machine cycle is essential for the execution of machine direction by the computer processor as the device execution is based on the machine cycle. If the direction is not executed accurately the execution can be deteriorated by the processor.

If a document is stored on a file server but team members can edit the document anonymously, the content on the file server is:_______a. shared content with version management b. shared on Google drive c. shared content with no control d. shared with the public e. shared content with version control
Answer:
d
Explanation:
Because a decimal number
If a document is stored on a file server but team members can edit the document anonymously, the content on the file server is considered to be a: c. shared content with no control.
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives. Thus, it offer or avail individuals and businesses a fast, effective and efficient way of providing services to their clients over the internet.
Generally, cloud computing comprises three (3) service models and these are;
Infrastructure as a Service (IaaS). Software as a Service (SaaS). Platform as a Service (PaaS).A file server can be defined as a type of computer that centrally stores, manage and fetch all data files (audio, image, text and video) as they are requested over the internet or network by end users (clients).
An access control refers to a security technique that is used to determine whether a user has the minimum requirements (credentials) to access, use or view resources such as documents on a computer by ensuring they are who they claim to be (authentication).
In this context, when a document (content on a computer) is shared on a file server without the implementation of an access control, the file can be anonymously edited by end users because it won't ask or request for authentication.
However, a shared content on a file server with an access control would only grant permission to authorized users while denying other users access to edit or modify its content.

Bash script which takes array as an input of size 10 bind its even indexes to accept even values and odd indexes to accept odd numbers only is explained below in detail.
Explanation:
Even digits at an even table and odd digits at an odd table
Given an array of size n comprising an equal number of odd and even digits. The difficulty is to manage the numbers in such an approach that all the even digits get the even table and odd digits get the odd table. The necessitated auxiliary space is O(1).
Examples :
Input : arr[] = {8, 5, 1, 12, 6, 3}
Output : 3 6 1 12 5 8
Input : arr[] = {7, 9, 10, 19, 13, 18, 21, 20, 4, 14}

what must be the same for each variable in an array in compiled languages?
The data type must be the same for each item in the array.
Assume that the message M has to be transmitted. Given the generator function G for the CRC scheme, calculate CRC. What will be the bit sequence that actually gets transmitted?
Let the message be M : 1001 0001 and the generator function is G : 1001
Solution :

How does entering search terms in quotation marks affect search results?
edhesive in JAVA Write a method that takes a String parameter. If the String has a double letter (i.e. contains the same letter twice in a row) then it should return true. Otherwise, it should return false.
This method must be named hasRepeat() and have a String parameter. This method must return a boolean.
I've included my code in the picture below. Best of luck.
The method is an illustration of loops and conditional statements.
Loops are used for repetitive operations, while the execution of a conditional statement is based on its truth value.
The hasRepeat() method in Java, where comments are used to explain each line is as follows:
//This defines the hasRepeat() method
public static boolean hasRepeat(String str){
//This initializes the previous character
char prevC = ' ';
//This iterates through the characters of the string str
for(int i = 0; i<str.length();i++){
//This gets the current character
char currC = str.charAt(i);
//If the current character and the previous character are the same
if(currC == prevC){
//Return true
return true;
}
//Assign the current character to the previous character
prevC = currC;
}
//Return false, it the string contains no repetitive character
return false;
}
At the end of the method, the program returns true or false.

Write a function that returns a pointer to the maximum value of an array of float ingpoint data: double* maximum(double* a, int size) If size is 0, return NULL.
Answer:
double * maximum( double arr[], int size){
int max = 0;
if ( size == 0){
return 0;
} else {
for (int i = 1; i < size; i++){
if (arr[i] > arr[0]){
max = arr[i];
} else {
max = arr[0];
}
}
return max;
}
}
Explanation:
The C++ source code above returns the maximum value of an array as a pointer. The function accepts two parameters, the array in question and the size of the array. The for loop iterates over the items in the array and checks for the largest, which is returned as a pointer since the function "maximum" is defined as a pointer to the floating-point number memory location.
