方法一：使用sprintf函数将int转换为string。sprintf函数可以将一个或多个变量按照指定的格式输出到一个字符串中。要使用sprintf函数，需要包含stdio.h头文件。例如，要将int类型的变量num转换为string类型的变量str，可以使用以下代码：方法二：使用atoi函数将string转换为int。atoi函数可以将一个字符串表示的整数转换为...
Using Microsoft's String: int i;String str=i.toString();Thursday, November 26, 2015 11:04 PMUsing Microsoft's String: int i; String str=i.toString();Huh? That doesn't look like C++ to me. Are you confusing this with C++/CLI?
天师曰:“我C风格严重。” 4.to_string 好了最后一个方法就是我昨天面向百度的最重要的发现。这是C++11标准中string类下的一个新函数。 to_string - C++ Reference //to_string demo#include<iostream>#include<string>intmain(){usingnamespacestd;intnumber=85;stringnumberstr;numberstr=to_string(number);...
一、int转string 1.c++11标准增加了全局函数std::to_string: string to_string (int val); string to_string (long val); string to_string (long long val); string to_string (unsigned val); string to_string (unsigned long val); string to_string (unsigned long long val); ...
