Sum and average with call by reference

 #include<stdio.h>


void sumAndAvg(int a, int b, int *sum, float *avg){

    *sum = a +b;

    *avg = (float)(*sum)/2;

}


int main(){

    int i, j, sum;

    float avg;

    i = 3;

    j = 6;

    sumAndAvg(i, j, &sum, &avg);

    printf("The value of sum is %d \n", sum);

    printf("The value of avg is %f \n", avg);

    

    return 0;
