Question

I’m looking for a string indexof function from the std namespace that returns an integer of a matching string similar to the java function of the same name. Something like:

std::string word = 'bob'; int matchIndex = getAString().indexOf( word ); 

where getAString() is defined like this:

std::string getAString() { ... } 

Answer 1

Try the find function.

Here is the example from the article I linked:

 string str1( 'Alpha Beta Gamma Delta' );  string::size_type loc = str1.find( 'Omega', 0 );  if( loc != string::npos ) {    cout << 'Found Omega at ' << loc << endl;  } else {    cout << 'Didn't find Omega' << endl;  }
