istringstream 根据空格分隔字符串 string转int i = stoi(s) int转string s = to_string(i) 示例如下
#include <iostream> #include <string> #include <sstream> using namespace std; int main(){ string s = "a 5 *"; istringstream iss(s); string tmp; while(iss >> tmp){ cout << tmp << endl; } int i; i = stoi("1"); cout << i << endl; cout << to_string(i) << endl; return 0; } /* 输出 a 5 * 1 1 */转载于:https://www.cnblogs.com/qbits/p/10980466.html
