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] );

Thnx, im still having trouble with this damn prog, i know this is a little cheecky, but ill put my source file up and if anyone can be bothered to have a look and tell me where im going wrong id be really grateful

thnx

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

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

strcmp is in string.h

thanks alot m8, i owe you one
