#include<stdio.h>
void main (){
   int a,b,c,d;
   printf("Enter the values of a,b,c,d: ");
   scanf("%d%d%d%d",&a,&b,&c,&d);
   if(a>b){
      printf("%d is the largest",a);
   }
   else if(b>c){
      printf("%d is the largest",b);
   }
   else if(c>d){
      printf("%d is the largest",c);
   }
   else{
      printf("%d is the largest",d);
   }
}

Output

When the above program is executed, it produces the following result −

Enter the values of a,b,c,d: 2 3 4 5
5 is the largest
