[C++知识库]c++ split 根据字符分割字符串

c++ 实现python的功能：os.path.basename(img_path)

#include <iostream>
#include <string>
void _split(const std::string &s, char delim, std::vector<std::string> &elems) {
    std::stringstream ss(s);
    std::string item;

    while (getline(ss, item, delim)) {
        elems.push_back(item);
    }
}
std::vector<std::string> split(const std::string &s, char delim) {
    std::vector<std::string> elems;
    _split(s, delim, elems);
    return elems;
}

int main()
{
    std::string img_path = "img_dir/1.jpg";
    std::vector<std::string> elems;
    elems = split(img_path, '/');
    int num = elems.size();
    std::cout << elems[num-1] << std::endl;
    return 0;
}
