用于获取行数作为值的宏

#include <stdio.h>

int main() {
    printf("当前行数：%d\n", __LINE__);
    return 0;
}

public class Main {
    public static void main(String[] args) {
        StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
        int lineNumber = stackTrace[1].getLineNumber();
        System.out.println("当前行数：" + lineNumber);
    }
}

import inspect

def get_line_number():
    frame = inspect.currentframe()
    return frame.f_lineno

print("当前行数：", get_line_number())
