To find the greater among three numbers with an algorithm , flowchart and program.

Algorithm:

Step 1: Start


Step 2: Input value of a,b,c


Step 3: If a > b then

                     Assign a to max

             Otherwise

                     Assign b to max
 
Step 4: If c > maximum then
 
                     Assign c to max

Step 5: Display max

Step 6: Stop

Flowchart:

Program: 

#include<stdio.h>

int main()

{

   int a,b,c,max;

   printf("\n Enter three numbers ");

   scanf("%d%d%d",&a,&b,&c);

   if(a>b)

    {
   
          max=a;
    }

   else

   {
  
         max=b;
   } 

   if(c>max)

   {
        
         max=c;

   }


   printf("\n greater number is %d \n", max);
 
   return (0);

}

Output:

 
Enter three numbers 2 3 4
 
greater number is 4
