This C program allows a user to input the number of integers they want to add, then prompts them to enter that number of integers. It uses a for loop to iterate through each input integer, adding it to a running sum variable, and after the loop prints out the final total sum of all entered integers.

1. C program to add n numbers
#include<stdio.h>
//#include<conio.h>
int main()
{
int n, sum = 0, c, value;
printf("Enter the number of integers you want to addn");
scanf("%d", &n);
printf("Enter %d integersn",n);
for (c = 1; c <= n; c++)
{
scanf("%d", &value);
sum = sum + value;
}
printf("Sum of entered integers = %dn",sum);
return 0;
}
Output of program:
