a>b?a:b  means if a is greater than b then output is a otherwise b. Function " max_of_four " will return the value of maximum value out of four values.

#include <stdio.h>

int  max_of_four(int a,int b,int c,int d)

{ 

    int m,n,x;

    m=a>b?a:b;

    n=c>d?c:d;

    x=m>n?m:n;

    return x;

}

int main()

 {

    int a, b, c, d;

    scanf("%d %d %d %d", &a, &b, &c, &d);

    int ans = max_of_four(a, b, c, d);

    printf("%d", ans);

    

    return 0;

}
