Algorithm to Find Sum and Average of N Numbers

Use the following algorithm to write a program to find the sum and average of n numbers; as follows:

  • Step 1: Start Program.
  • Step 2: Read the term of n numbers from the user.
  • Step 3: Then read one by one numbers and calculate sum and average of n numbers using for loop or while loop.
  • Step 4: Print sum and average n number.
  • Step 5: Stop Program.

C Program to Find Sum and Average of N Numbers using For Loop

#include <stdio.h>

int main()
{   
    int num, sum = 0, n;
    float avg;
    
    printf("Please Enter term of n number:-");
    scanf("%d", &n);
    for(int i = 1; i <= n; i++)
    {
        printf("Number %d = ", i);
        scanf("%d", &num);
        sum = sum + num;
    }

    avg = sum / n;

    printf("\nThe Sum of n Numbers     = %d", sum); 
    printf("\nThe Average of n Numbers = %.2f\n", avg);
}

The output of the above c program; as follows:

Please Enter term of n number:-5
Number 1 = 1
Number 2 = 2
Number 3 = 3
Number 4 = 4
Number 5 = 5
The Sum of n Numbers     = 15
The Average of n Numbers = 3.00

C Program to Find Sum and Average of N Numbers using While Loop

#include <stdio.h>

int main()
{   
    int num, i, sum = 0, n;
    float avg;
    
    printf("Please enter term of n numbers :- ");

    scanf("%d", &n);

    i = 1;

    while(i <= n)
    {
        printf("Number %d = ", i);
        scanf("%d", &num);
        sum = sum + num;
        i++;
    }

    avg = (float)sum / n;

    printf("\nThe Sum of n Numbers     = %d", sum); 
    printf("\nThe Average of n Numbers = %.2f\n", avg);
}

The output of the above c program; as follows:

Please enter term of n numbers :- 5
Number 1 = 1
Number 2 = 2
Number 3 = 3
Number 4 = 4
Number 5 = 5
The Sum of n Numbers     = 15
The Average of n Numbers = 3.00
