    Equivilant to BASICS Instr function (a string inside a string)

    Im wondering what the equivilant to BASIC instr function is. what it does is takes 2 parameters (string 1, string 2) then returns true if the text from string 2 is also in string 1 (or vice-versa, im not positive) then it returns false if theyre not. Im wondering what the equivilant to this in C++ is, its about the only thing keeping me from finishing my project. ive tried strcmpi, but i cant get it to tell if one string is 'inside' the other. thanks for any help!

    you could use:
    Code:
    char *strstr( const char *string, const char *strCharSet );
    Quidquid latine dictum sit, altum sonatur.
    Whatever is said in Latin sounds profound.

    thanks, but i still cant get it to work...heres some code:


    char *instr;
    ...
    instr=strstr(question[i],say);
    if(instr!=NULL)
    ...
    ...

    now even if say is in question[i] and vice-versa (it loops through all of the questions) it still wont continue, it will just skip the whole if statement. any ideas?
