Toupper() function prototype is declared in . stream This means that program flow may not necessarily move from one statement to the next one, but rather some alternative portions may need to be pass into or bypassed from, depending on the outcome of the conditional statements. At any particular instance, only the top of the stack is accessible, which means that in order to retrieve data that is stored inside the stack, those on the upper part should be extracted first. A misplaced symbol, or lack of symbol, somewhere within a line of code can also lead to syntax error. All reserved words must be written in lowercase; otherwise the C compiler would interpret this as unidentified and invalid. Reserved words are words that are part of the standard C language library.
