hi, Im using dev c++ and I cant use the stoi function and I kinda need to use it. I searched how to fix that problem in google but it doesnt seem to work.

is there an alternative way to have the same function as stoi. i cant use atoi because i want to convert a string and atoi requires const char * to be used.

thank you.

Solution 1

The very documentation[^] suggests a workaround: stoi internally calls std::strtol(str.c_str(), &ptr, base) and your code could do exactly the same (you may also call atoi(str.c_str()) however strtol is a superior alternative to atoi).

By the way, if you really need C++11 features, then you have either to update the compiler used by Dev-C++ or, possibly, enable the C++11 extensions on the installed compiler (for instance g++ provides the -std=c++11 option).

Plese, see this Stack Overflow question: "orwell dev-c++ support c++11"[^].
