Here's some hypothetical pseudocode. I'm trying to understand the relationship between function prototypes and main:
1. Can function prototype A call int x? Or does int x need to be defined in A?Code:function main{ int x int y } // end function main function prototype A int a function prototype B int b
2. Can function B use int a?
3. Is it possible to call prototype A, return int a to main, and call int a inside prototype B?
