使用std :: sregex_token_iterator 在这种方法中,基于正则表达式匹配进行标记化。当需要多个定界符时,更适合用例。 下面是一个简单的C ++程序,用于显示std :: sregex_token_iterator的用法: #include <iostream> #include <regex> #include <string> #include <vector> std::vector<std::string>tokenize( const...
tokenize 的能力很 trivial 这里可以看出,它是无法同时处理两个字符串的,如果一个字符串处理了一半,再使用另一个字符串作为 str 参数的话,内部存储位置的指针会被重新初始化,进而把原先字符串的处理进度丢失掉。可以使用函数 strtok_r 来解决这个问题,它接受一个指针参数,用来保存当前的字符串处理位置。 由于每调用...

and because of every SDS string implicitly adding a null term at the end of the string regardless of the actual content of the string, SDS strings work well together with C strings and the user is free to use them interchangeably with other std C string functions that access the string in...
要识别C语言中整数输入的具体数字,可以使用scanf函数进行输入读取。以下是一个简单的示例代码: 代码语言:c 复制 #include<stdio.h> int main() { int num; printf("请输入一个整数:"); scanf("%d", &num); printf("您输入的整数是:%d\n", num); return 0; } 在这个示例中,我们使用scanf函数读取用户...

As usually the function can work with both SDS strings or normal C strings. The first two argumentssandlenspecify the string to tokenize, and the other two argumentssepandseplenthe separator to use during the tokenization. The final argumentcountis a pointer to an integer that will be set to...
std::string.c_str()returns aconstchar*. There are 2 versions ofgetlinethat apply here. The first is the non-member functionistream& getline (istream& is, string& str);(http://www.cplusplus.com/reference/string/string/getline/).In this case, you need to pass a reference to a std::...
