How do you put a Standard Input into your program correctly?

Question

I was trying to use Perl programing a txt use a sample as an example when it had <STDIN>; after the equal symbol from the element, it had an error issue.

Answer 1

The example here works just fine.

Did you set the OnlineGDB's language to Perl (top right corner)?

If your issue persists, please, share your project (orange SHARE button two to the right of the RUN button).

Answer 2

#include <stdio.h>

int main() {
    int number;

    printf("Enter a positive integer: ");
    scanf("%d", &number);  // Read an integer from standard input

    printf("You entered: %d\n", number);  // Output the entered number

    return 0;
}
