C programming Beginner Question (More Helpful if provide me with the code)

Problem : Who is the winner? (Level 1)

• Problem description
  Alice and Bob are playing a game. Both of them write down an integer number. If the sum oftwo integers is a square of an integer, Alice wins the game. If the reversed number of the sumis a square of an integer, Bob wins. If neither of them wins, or both of them win, it is a tie. Forexample, Alice wrote an 8, Bob wrote a 10. 18 is not a square of any integer. But 81 is a squareof 9. So Bob is the winner.
  Write two functions int is_square(int num) and int reverse(int num) to check whether num is asquare number or not and reverse num, respectively. Then the program should call bothfunctions and output the winner information.
• Input & output requirements
  Input two positive integer numbers. The output should follow the format as shown in sample
  results.
• Sample resultsSample 1
  8 10↲Bobs winsSample 22 2↲
  Tie

So what have you managed to do so far?

Can you for example input two numbers?
Can you add them?

insert

Code:

---

#include<stdio.h>
int main(){
        int a,b,sum,rev=0,remainder,i;
        printf("Please enter the two integers:");
        scanf("%d%d",&a,&b);
       
        sum=a+b;
        while(sum!=0){
                remainder=sum%10;
                rev=rev*10+remainder;
                sum/=10;
        }
       
        for(i=0;i<=sum;i++){
        if(sum==i*i){
                printf("Alice wins");
        }
        else if(rev==i*i)
        {printf("Bob wins");
        }
        return 0;
        }
}

I am struggling here...

But I don't know why when I input 8 and 10, it still output Alice wins. It should be Bob wins.

A couple of points.

1. You need to move bits of code into functions.
> "Write two functions int is_square(int num) and int reverse(int num)"

2. Indentation matters - yes, really!

Code:

---

#include<stdio.h>
int main()
{
  int a, b, sum, rev = 0, remainder, i;
  printf("Please enter the two integers:");
  scanf("%d%d", &a, &b);

  sum = a + b;
  while (sum != 0) {
    remainder = sum % 10;
    rev = rev * 10 + remainder;
    sum /= 10;
  }

  for (i = 0; i <= sum; i++) {
    if (sum == i * i) {
      printf("Alice wins");
    } else if (rev == i * i) {
      printf("Bob wins");
    }
    return 0;
  }
}

So for example
- you mess up the sum value, trying to compute the rev value.
- your return 0; is inside the for loop, so your loop runs only once anyway.
- Alice always wins, because you managed to make sum = 0 trying to compute rev.

And change your scanf to

Code:

---

  scanf( "%d %d", &a, &b );
