Answer 1

#include <stdio.h>
#define MAX_OF_THREE(a,b,c) (a>b)?((a>c)?a:(c>b)?c:b):((b>c)?b:c)
int main()
{
    int a=7,b=5,c=5;
    printf("maxm no %d\n",MAX_OF_THREE(a,b,c));
}

Answer 2

include<stdio.h>

main()
{
int a=10,b=20,c=30;
a>b?a>c?printf("a is greater\n"):printf("c is greater\n"):b>c?printf("b is greater\n"):printf("c is greater\n");
