Regex of two substrings in C++

Question

Hi

Refer code below:

/////////////////////////////////////////////////
string name = "checkRealEditorWithCheckbox";

if (name.find("check") != std::string::npos
&&
name.find("Editor") != std::string::npos
)
cout << "Matched\n";
else
cout << "Not matched\n";

///////////////////////////////////////////

Above code works fine as I am trying to find whether string has check and Editor both. Due to this, I have to do find operation twice which I am trying to avoid and want to do once only.

Is there a way to do so? Can regex help here? If yes, how?

Answer 1

// Be aware that regex is notoriously slow in C++. Your original code is faster.

#include <iostream>
#include <regex>
using namespace std;

int main() {

string name = "checkRealEditorWithCheckbox";

cout << (regex_search(name,regex("check.*Editor")) ?
"Matched\n" : "Not matched\n");

}
