如何实现“加载屏幕”？

Question

有没有办法调用loading_screen()，然后在三秒后清屏，然后进入程序？

#include <stdio.h>
    
    void loading_screen() {
        printf("\n*\t *\t *\t *\t *\t *\t *\t *\n* Welcome to your blah blah! *\n*\t *\t *\t *\t *\t *\t *\t *\n\n");
    }
    
    void starting_screen() {
        printf("1. add new recipe\n");
        printf("2. search for recipe\n");
        printf("3. delete recipe\n");
    }
    
    int main(int argc, char *argv[]) {
        loading_screen();
        starting_screen();
        return 0;
    }
