本例主要演示C语言中的各种string操作方法,包括std::tolower,std::toupper,std::isalpha,std::isalnum,等等。 代码如下,...
s2.stringup();//converts string to uppercasecout <<"The string\n"<< s2 <<"\ncontains"<< s2.has('A')<<"'A' characters in it.\n"; s1="red";//String(const char *),//then String & operator=(const String&)String rgb[3] = { String(s1), String("green"), String("blue")...
find_first_of("!@#$%^&*()"); if (index != std::string::npos) { std::cout << "特殊字符的索引为: " << index << std::endl; } else { std::cout << "未找到特殊字符" << std::endl; } return 0; } 在上述示例代码中,我们使用了find_first_of函数来查找字符串中第一个...

数值类型转字符串 C++11以前没有直接的数值类型转字符串的函数,这里提供一些: std::string itoString(int i) { char buf[30] = {0}; sprintf...字符串根据特定字符拆分成数组通用函数 split是其他语言中将字符串转化为数组的常用函数,C++中却没有,这里提供一个通用函数,可以将字符串根据特定字符拆分成数组:...
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 the output } return 0; } Name: getline 这个函数接受两个參数:一个输入流对象和一个 string 对象。getline 函数从输入流...
