    Help Converting a String to uppercase using TOUPPER()

    Hi all, im new on this board and just thought id give it a try and see if any of you lot could help me out with my problem.

    im trying to convert a string IE "degrees" to uppercase letters using the toupper statement, this works with single chars but not with a string.

    Does anyone know what im doing wrong or why it wont work, or another method ive overlooked.

    Cheers

    e.g. temp = toupper(temp);

    You use a for loop to apply toupper to each char in turn
    string[i] = toupper( string[i] );
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    > sign == "CELSIUS"
    This is not how you compare strings

    Do this
    if ( strcmp( sign, "CELSIUS" ) == 0 ) {
    }

    strcmp is in string.h
