如何在C++中连接string + int + string？

Question

如何连接i + name + letter + i？

for(int i = 0; i < 10; ++i){

    //I need a const char* to pass as a parameter to another function
    const char* name  = "mki";

    //The letter is equal to "A" for the first 2, "B" for the second 3,
    //"C" for the following 4 ...
    const char* final_string = ???
}

我已经尝试过使用:

std::to_string(i)

但我说错了

对于std,to_string未定义

我正在使用Visual C++.

您有较旧版本的VC++,它不支持当前的C++标准.在这种情况下,你必须以老式的方式做到这一点.

#include <sstream>

std::ostringstream o;

o << "mki" << i << "abc";

std::string s=o.str();
