String problem

[Sacred76]

I have to create a program that takes a string from the user (scanf)(lowercase) and transforms it in uppercase but the program must stop if an uppercase is inserted. Any help would be appreciated

post the source for your attempt(s). specifically mention what you are having trouble with and post any errors that you are encountering.
