How to clear the console screen in C language?

In C language, there are several methods to clear the console content.

1. clear the console
2. clear the system display

#include <stdlib.h>

int main() {
    // 清屏
    system("cls");  // Windows系统
    // system("clear");  // Linux系统

    return 0;
}

1. Clear the screen.

#include <stdio.h>

int main() {
    // 清屏
    printf("\033[2J");

    return 0;
}

It should be noted that the method of using escape characters to clear the screen may not work on some consoles, so it is recommended to use system commands instead.
