Question

Ask a user for three positive integer numbers. Use an input validation loop to make sure that all numbers are positive, ask again if not. Determine the smallest, middle and largest number and display them with proper labeling (Smallest=AA, Middle=BB, Largest=CC). Write this program in C

Answer 1

#include <stdio.h>

int main() { 
   int a,b,c,Smallest,Middle,Largest;
   do{
      printf("Enter value for a: ");
      scanf("%d",&a);
   }while(a<=0);
   
   do{
      printf("Enter value for b: ");
      scanf("%d",&b);
   }while(b<=0);
   
   do{
      printf("Enter value for c: ");
      scanf("%d",&c);
   }while(c<=0);
   
   if(a<b && a<c){
      Smallest = a;
      if(b<c){
         Middle = b;
         Largest = c;
      }
      else{
         Middle = c;
         Largest = b;
      }
   }
   else if(b<c){
      Smallest = b;
      if(a<c){
         Middle = a;
         Largest = c;
      }
      else{
         Middle = a;
         Largest = b;
      }
   }
   else{
      Smallest = c;
      if(b<a){
         Middle = b;
         Largest = a;
      }
      else{
         Middle = a;
         Largest = b;
      }
   }
   
   printf("Smallest=%d, Middle=%d, Largest=%d",Smallest,Middle,Largest);
   return 0;
}
