    Word from a string...

    Hello:
    I have what is probably a simple question, although I have searched hard for an example and have found none on the Net thus far. I am working on the beginnings of a program which will rely heavly upon the ability for the computer to scan the typed input from a user; a particular (or "trigger word) if present in the input string should be found and selected (should it exist at all) This word when discovered will initiate a response. Example: The trigger word is "feel"// user inputs "I do not know how you feel about this but..." Program reads input and captures "feel" in turn causing reaction.
    I am the type of person that hates to ask for help (I'd rather figure it out myself, but...) Any help would be greatly appreciated.
    Cheers

    after getting the complete line of text you could separate each word by using the spaces, then, each word is placed in a certain array and compare each one with the original word, I believe the function that recognizes spaces is in ctype.h

    Thank-you, louis_mine.
    I have come across that today online, I believe, and I may have been overlooking other info as well. I am somewhat new to programming and I absolutely love it to the point of obsession at times. Thanks again.

    One question:
    If I parse a string and seperate the words into specific, reserved arrays, I then could compare them to the trigger word, say, "feel". Would "feel" need to be declared as a const var? Also, are sub-strings able to be compared like intergers, "cat==cat" or "dog!=cat"?

    feel can be declared as a char*, i am not sure if as constant.
    You can compare strings, however it has to be for example:

    if ("cat"=="cat") //using " " for strings, simple characters like just one letter use ' ' .

    I hope that helps

    Actually, to compare strings, your best bet is the strcmp() function.

    I think strcmp( ) is specific to the <cstring> library.. However when using the <string> library, the binary operators such as == and += should be used.
