错误记录C++预处理器宏__LINE __,__ FUNCTION__

#include<iostream>

int main() {
    std::cout << "This is line " << __LINE__<< std::endl;
    std::cout << "This is line " << __LINE__<< std::endl;
    std::cout << "This is line " << __LINE__<< std::endl;
    return 0;
}

This is line 5
This is line 6
This is line 7

#include<iostream>

void foo() {
    std::cout << "This function is " << __FUNCTION__<< std::endl;
}

void bar() {
    std::cout << "This function is " << __FUNCTION__<< std::endl;
}

int main() {
    foo();
    bar();
    return 0;
