functions unit structure objectives introduction function calls type conversion functions math functions adding new functions definitions and uses flow of execution parameters and arguments variables and parameters are local stack diagrams fruitful functions and void functions why functions importing with fromreturn valuesincremental development boolean functions more recursionleap of faithchecking types summary references unit end exercise objectives after reading through this you will be able to to understand and use the function calls to understand the type conversion functions to understand the math function to adding new function to understand the parameters and arguments to understand the fruitful functions and void functions to understand the boolean functionsrecursionchecking types etc introduction one of the core principles of any programming language is"don' repeat yourselfif you have an action that should occur many
