从函数的子函数退出到main

#include <stdio.h>

void subFunction() {
    printf("This is a sub function\n");
    // 执行完子函数后回到主函数
}

int main() {
    printf("This is the main function\n");
    subFunction();
    printf("Back to the main function\n");
    return 0;
}

def sub_function():
    print("This is a sub function")
    # 执行完子函数后回到主函数

def main():
    print("This is the main function")
    sub_function()
    print("Back to the main function")

if __name__ == "__main__":
    main()
