A simple C function

Greetings, I want to write a simple function(s) using C that utilizes toupper() that accepts string input (my choice of string size), and converts lower-case input to upper-case input. I need this function to accept input and return modified input (char ToUpper(char *)?). If an upper-case string is input, then the output is upper-case as well. If possible, I want to have this function convert every lower-case character after every whitespace to upper-case. I am going to call this function from within a larger function. Example: int main() { void larger_function() { line = ToUpper/*function that uses toupper()*/ } void view(char line) return 0; } ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
