My issue

include
using namespace std;

int main() {
int num;

// Ask for user input
cout << "Enter a number: ";
cin >> num;  // User input for 'num'

// Edge case check: if num is 0, no output should be printed
if (num == 0) {
    return 0;  // Exit the program without printing anything
}

int a = 0;  // Initialization of 'a' to 0

// Loop: Print 'a' while it is less than 'num'
while (a < num) {
    cout << a << endl;  // Print 'a' on a new line
    a++;  // Increment 'a' by 1
}

return 0;

}

My code

#include <iostream>

using namespace std;

int main() {
    int num;

    // Ask for user input
    cout << "Enter a number: ";
    cin >> num; // User input for 'num'

    // Edge case check: if num is 0, no output should be printed
    if (num == 0) {
        return 0; // Exit the program without printing anything
    }

    int a = 0; // Initialization of 'a' to 0

    // Loop: Print 'a' while it is less than 'num'
    while (a < num) {
        cout << a << endl; // Print 'a' on a new line
        a++; // Increment 'a' by 1
    }

    return 0;
