Introduction to Program

In this problem statement, we have three number and out of these three number we have to find, which is bigger or largest. this can be achieve by comparing these three number with each other.

Algorithm

Step1: declare three variable named A, B and C

Step2: Read the value of A, B and C from user

Step3: if A>B then

                if A > C then

                print A is greater

                   otherwise

                print C is greater

            otherwise

                 if B > C then

                print B is greater

                   otherwise

                print C is greater

Step4: Exit

Program in C language

#include<stdio.h>
#include<conio.h>
void main()
{
     int num1,num2,num3;
     printf("enter any three number\n");
     scanf("%d %d %d",&num1,&num2,&num3);
     if(num1>num2)
     {
          if(num1>num3)
          {
            printf("%d is greater than %d ,%d",num1,num2,num3);
          }
          else
          {
            printf("%d is greater than %d ,%d",num3,num1,num2);
          }
     }
     else
     {
         if(num2>num3)
         {
             printf("%d is greater than %d ,%d",num2,num1,num3);
         }
         else
         {
             printf("%d is greater than %d ,%d",num3,num1,num2);
         }
     }
}

OutPut

enter any three number

23 

3

24

24 is greater than 23, 3
