Full prototype:
int puts(const char*);  
Purpose and Notes:
Writes the string associated with the const char* of the first and only function argument to the stream associated with stdout. It also appends a newline character to the end of it.
Returns:
int- On a successfull call to the function it ruturns a non-negative number. Otherwise it returns EOF.
Argument 1:
const char*- A string that you want to write to standard out. Remember that it automatically adds a newline character to the string, so if there is already one in the string then it will print with two newline characters.
