Problem while running C

[muhmdfayasek]

I run a simple code, just to test acode for C. For recommend acode to my friends to learn C. When i run it, it shows a problem, didn't run perfectly.
int value; printf("Enter a value: "); scanf("%d", &value); printf("You entered: %d\n", value);

It only execute after i entered the value. Even the "Enter a value" portion. But if it's just a code with only a "printf" statement, it's fine, works perfectly. But not in code like given.

What is the problem. In the code runner or in my phone or in my code.

Here the images

Actually you need to flush(fflush(stdout)) the buffer as Acode uses alpine environment which uses musl instead of glic and musl is minimal and highly efficient, It typically follows a stricter buffering rule: if there is no newline (\n) and the buffer isn't full, it doesn't send the text to the screen yet.

#include <stdio.h>

int main() {
    int value;
    printf("Enter a value: ");
    
    // This forces the text out of the buffer and onto the screen immediately
    fflush(stdout); 

    if (scanf("%d", &value) == 1) {
        printf("You entered: %d\n", value);
    } else {
        printf("Invalid input. Please enter an integer.\n");
    }
    return 0;
}
