how to check string start in C++

Question

Is there any way in C++ to check whether a string starts with a certain string (smaller than the original) ? Just like we can do in Java

bigString.startswi         


        

Answer 1

The simplest approach would be:

if ( smallString.size() <= bigString.size()
    && std::equals( smallString.begin(), smallString.end(), bigString.end() )

(This will also work if one of the two, or both, is a vector. Or any other standard container type.)
