Question

I need to set a boolean based on whether a string is present in my data dictionary, with a structure of:

std::map< string, foo > dd

If the string I’m looking for is there, then the boolean is true, and vice versa. Can someone help me with how do I do this in C++?

Thanks.

Answer 1

Suppose data dictionary is std::map< string, foo > dict;

bool const word_present( string str_word, std::map< string, foo > &dict)
{
    return (dict.find( str_word ) != dict.end());
}
