2、多个单词使用函数std::getline(std::cin, s)请看以下代码: #include <iostream> #include <string> int main() { std::string line; // empty string while(std::getline(std::cin, line)) { // read line at time until end-of-file std::cout << line << std::endl; // write s to t...
std::string s = "hello world"; std::cout<<s<<std::endl; for (std::string::size_type ix = 0; ix != s.size(); ++ix) s[ix] = '*'; std::cout<<"Now s is:"<<s<<std::endl; std::cout<<"s's len is:"<<s.size()<<", s[12]="<<s[100]<<std::endl; return 0...

for(inti=0;i<10;i++){std::cout<<i<<std::endl;} while循环:当满足特定条件时,重复执行一段代码。 代码语言:cpp 复制 intj=0;while(j<10){std::cout<<j<<std::endl;j++;} Java Java中的循环与C++和C#类似,也有for和while循环。 for循环:在给定的范围内重复执行一段代码。
