Question

How would I write the following program in C programming language?

Function header: int sumsort(int *a, int *b, int *c)

This function should arrange the 3 values in the memory locations pointed to by a, b, and c in ascending order and also return the sum of the contents of the memory locations a, b, and c.

#include<stdio.h>
int sumsort(int *a, int *b, int *c){
    if(*a>*b) {
            int temp=*a;
            *a=*b;
            *b=temp;
        }
        if(*b>*c) {
            int temp=*b;
            *b=*c;
            *c=temp;
        }
        if(*a>*b) {
            int temp=*a;
            *a=*b;
            *b=temp;
        }
    return (*a) + (*b) + (*c);
}
int main(){
    int a=10,b=3,c=15;
    int sum=sumsort(&a,&b,&c);
    printf("%d %d %d = %d ",a,b,c,sum);
}
