C Program to Find Average of Two Numbers

Write a C Program to Find Average of Two Numbers with an example. This C example allows to enter two Integers and calculates the sum and average of that numbers.

#include <stdio.h>

int main()
{
int number1, number2;
float res;

printf("Enter the First Number to find = ");
scanf("%d",&number1);

printf("Enter the Second Number to find  = ");
scanf("%d",&number2);

int sm = number1 + number2;

res = sum/2; //(float)sum/2;

printf("The Sum of %d and %d     = %d\n", number1, number2, sm);
printf("The Average of %d and %d = %.2f\n", number1, number2, res);

return 0;
}

C average of two numbers output

Enter the First Number to find Average = 20
Enter the Second Number to find Average = 60
The Sum of 20 and 60     = 80
The Average of 20 and 60 = 40.00

In this C program, we created a new function that calculates and returns the average of given two numbers.

#include <stdio.h>

float calcAverageofTwo(int a, int b)
{
return (float)(a + b)/2;
}

int main()
{
int number1, number2;

printf("Enter the First Number to find Average = ");
scanf("%d",&number1);

printf("Enter the Second Number to find Average = ");
scanf("%d",&number2);

float average = calcAverageofTwo(number1, number2);

printf("The Average of %d and %d = %.2f\n", number1, number2, average);

return 0;
}
