如何有两个函数调用对方C ++ [英] How to have two functions that call each other C++

问题描述

我有两个这样的函数，对if循环进行模糊处理：

I have 2 functions like this that does obfuscation on if loop:

void funcA(string str)
{
    size_t f = str.find("if");
    if(f!=string::npos)
    {
        funcB(str);        //obfuscate if-loop
    }
}

void funcB(string str)
{
     //obfuscate if loop
     funcA(body_of_if_loop);     //to check if there is a nested if-loop
}

如果我插入 funcB，则 funcA 将无法看到 funcB

The problem with this would be that funcA would not be able to see funcB and vice versa if I put funcB before funcA.

Would appreciate any help or advice here.

推荐答案

您想要的是转发声明。

void funcB(string str);

void funcA(string str)
{
    size_t f = str.find("if");
    if(f!=string::npos)
    {
        funcB(str);        //obfuscate if-loop
    }
}

void funcB(string str)
{
     //obfuscate if loop
     funcA(body_of_if_loop);     //to check if there is a nested if-loop
}
