Algorithm of find sum and average of three or 5 numbers

  • Step 1: Start Program
  • Step 2: Get the three or five numbers from the user.
  • Step 3: Define a variables “Avg” and “Sum”.
  • Step 4: Find sum and average of 3 or 5 numbers using the followig formulas:
    • sum = (a+b+c);
    • avg = (a+b+c)/3;
    • sum = (a+b+c+e+f);
    • avg = (a+b+c+e+f)/3;
  • Step 5: Show “sum ” and “Avg”.
  • Step 6:End Program.

C Program to Find Sum and Average of 3 Number

#include<stdio.h>
 
int main()
 
{
 
  float a,b,c,avg,sum;
 
  printf("Please enter 3 numbers ");
 
  scanf("%f%f%f", &a, &b, &c);
 
  sum=(a+b+c);
  avg=sum/3;
 
 
  printf("\Sum is  %f",sum);
  printf("\nAverage is  %f",avg);
 
  return 0;
 
}

The result of the above c program; as follows:

Please enter 3 numbers 1 2 3
Sum is  6.000000
Average is  2.000000
