Build a program which should have two classes Employee and Client. Employee should be in package ACP.Employee while Client class should be in ACP.Client. Employee class should have the following data members and Functionalities
Data members:
Employee Name
Father name
Emp ID (Number)
Job Category (Teacher, Officer, Staff, Labour)
Date of birth (Date)
Education (Matric, FSc, BS, MS, PhD)
Pay scale (number)
NIC (String)
Functionalities:
SetEmpInformation
UpdateEmpInformation
DeleteEmpInformation
Search and View Emp record by
Emp ID
Employee Name
Age
Job Catagory
Client class should have main function where it may have capacity of maximum 50 Employee records and You are only allowed to use arrays(list is not allowed).
User should be given choice whether to
Add New Employee record
Update Employee Information
Delete Employee Record
Search & view Employee
BY Emp ID
By Employee Name
By Age
By Job Catagory
Choices may be taken by using Input Message dialogs.
When user selects Add New Employee record, It must be kept in mind that no Teacher can have education lower than MS while No Officer can have lower than BS, No Staff can be lesser education than FSc and Labour should be with at least Matric Education. In the same manner for the Teacher pay scale can not be lesser than 18 while for the officer it cant be lesser than 17, the staff should be in between 11 and 16 and the pay scale for labour will be in between 1 and 10.
On update Employee Information, only education payscale and Job category can be updated.
When program is closed all the records should be saved into the file named as EmpDB.dat. all the objects must be serialized into the file. When the program starts if file EmpDB.dat is already present then user should have all required choices to apply on records available in file.
You will use java serialization to implement object serialization.
Note: Inputs should be taken by using Input dialogs and View should be by using showMessageDialog.
Emp ID should be unique and should not be set by user. It should be automatically assigned and Emp ID should start from 9000.

counter = 1
for i in range(1, 100) :
counter = counter + 1
print(counter)
Why is the answer 100 not 101
Answer:
The answer is 100 because the range() function in the for loop is set to go from 1 to 100, not 1 to 101. The range() function is inclusive of the start value and exclusive of the end value, so in this case it will only go up to 99, not 100. Additionally, the counter variable is not being incremented correctly within the for loop. The correct syntax for incrementing a counter variable would be "counter += 1" instead of "counter = counter + 1".
Write a complete C++ program named lab23.cpp that does the following.
The program fills a 5x4 array with 20 randomly generated two-digit positive integers so that the first 4 numbers occupy the first row, the next 4 occupy the next row and so on until the fifth row.
Make sure that your code generates different random integers when the program is run each time.
Print the array where each element in a row is separated by a space and each row is on its own line.
Print the maximum gap between the adjacent elements of each row. For example, if the elements in the first row of the array store 19, 20, 33 and 11, the maximum gap between adjacent elements in the first row is 22.

Software redundancy techniques
When a software system provides the same functionality through the execution of distinct pieces, it is redundant.
What is redundancy?Redundancy has two functions: passive redundancy and active redundancy. Both features use excess capacity to avoid performance decreases from exceeding specification limitations without requiring human involvement. Excess capacity is used in passive redundancy to mitigate the impact of component failures.
Many software engineering techniques have made extensive use of redundancy, such as fault-tolerance and reliability engineering, as well as self-adaptive and self-healing programs.
Therefore, It is redundant when a software system provides the same functionality through the execution of distinct pieces.

(Pick 5 Lotto) Write a program to simulate a pick-5 lottery game. Your program generates and stores 5 distinct random integers between 1 and 9 (inclusive) into an array. The program then prompts the user to enter 5 distinct integers between one and nine and stores the numbers into a second array. The program then compares and determines whether the two arrays are identical. If the two arrays are identical, then the user wins the game; otherwise, the program outputs the number of matching digits and their position in the array.
Use default_random_engine and unitform_int_distribution to generate the random numbers. See discussions to see engines and distributions details.
The way to write the program will be:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int seed;
printf("Enter an integer random seed: ");
scanf("%d", &seed);
srand(seed);
int comp_nums[5], user_nums[5];
int matchCount = 0;
int i=0;
printf("To play the Pick-5 game, enter five integers between 1 and 9 (inclusive): ");
for(i=0; i<5; i++) {
scanf("%d", &user_nums[i]);
}
printf("\n");
// generate comp_num
for(i=0; i<5; i++) {
comp_nums[i] = rand() % 9 + 1;
if(comp_nums[i] == user_nums[i]) {
matchCount++;
}
}
if(matchCount == 5) {
printf("\nCongratulations!!! You WIN!!!\n");
} else if(matchCount == 0) {
printf("You didn't match any numbers!\n") ;
} else {
printf("\nYou only matched %d numbers.\n", matchCount);
printf("Your numbers matched the Pick-5 numbers at position(s): ");
for(i=0; i<5; i++) {
if(comp_nums[i] == user_nums[i]) {
printf("%d ", i);
}
}
printf("\n");
}
printf("The winning numbers are: ");
for(i=0; i<5; i++) {
printf("%d ", comp_nums[i]);
}
printf("\n");
return 0;
}
How will the program be written?The appropriate steps include:
Define what the program should be able to do. It's also important to visualize the program running on the computer.
