劃分字符串插入逗號C++

Question

我有以下的字符串後數組： -

CoursesExams = HUM001,Technical Writing,28/4/2016,HallA;CSE121,Computer Programming,3/5/2016,HallB]

我希望每個;之後將其分割成一個數組。我如何使用C++來做到這一點？

Answer 1

使用std ::函數getline和字符串流：

std::string s = "HUM001,Technical Writing,28/4/2016,HallA;CSE121,Computer Programming,3/5/2016,HallB]"; 
std::vector<std::string> arr; 
std::istringstream str(s); 
std::string elem; 

// getline reads str stream until comma is found, then returns string in elem 
while(std::getline(str, elem, ',')) arr.push_back(elem); 

for (auto& s : arr) std::cout << s << "\n";
