invalid conversion from ‘const char*’ to ‘char’

C++ —用sstream把int转成string类型的方法

Author posted @ 2011年9月15日 08:59 in C/C++ , 4077 阅读

itoa是把整型转成char*,如果要转成string类型的话,可以用如下方法

In order to convert an int (or any other numeric type, e.g., float, double, etc.) to string, you can use:

#include <sstream>

int i = 5;
std::string s;
std::stringstream out;
out << i;
s = out.str();
