  #include<stdio.h>
  int main()
   {
       int num1,num2,num3;
       printf("Enter the first number :");
       scanf("%d",&num1);
       printf("Enter the second number :");
       scanf("%d",&num2);
       printf("Enter the third number :");                       
       scanf("%d",&num3);
          if(num1>num2 && num1>num3)
             {
                  printf("First number is greater than second and third number");
             }
           else if(num2>num3)
             {               
                  printf("Second number is greater than first and third number");
             } 
           else
             {
                printf("Third number is greater than first and second number");
             }  
       return 0;
   } 

Output :

  Program run first time:-
 

  Enter the first number :7
  Enter the second number :16
  Enter the second number :18
  Third number is greater than first and  second number
 
  Program run second time:-
 
  Enter the first number :30
  Enter the second number :20
  Enter the second number :15
  First number is greater than second and third number
