a) Write a program which asks the user to enter the name and age of persons in his group.
The number of persons is not known to the user in the beginning of the program. The user
keeps on entering the data till the user enters the age as zero. The program finally prints the
average age.July 17, 2021 in C and CPP
c) Write a program in ‘C’ which asks a user to input integers in an array of size 20. It then arranges the elements in decreasing order and prints the array.July 17, 2021 in C and CPP
b) Write a program which asks the user a number between 1 and 7 and prints the
corresponding day of the week. (1: Sunday, 2: Monday, …)July 17, 2021 in C and CPP

a) What is the output of the following program?
#include<stdio.h>
void fun(int*, int*);
int main()
{
int i=5, j=2;
fun(&i, &j);
printf("%d, %d", i, j);
return 0;
}
void fun(int *i, int *j)
{
*i = *i**i;
*j = *j**j;

compute the average of every third integer number lying between 1 and 100. Include
appropriate documentation.
