Function Declaration

• A function is declared to the computer using the following syntax:

• • return_variable name( input variables ) { commands }
  • • name : can be any text without numbers or symbols, as long as it is not used already
    • input_variables : inputs, if we want them
    • return_variable : output value, if we want one
    • commands : lines of code to execute when we call the function
  • we can have as many inputs as we want, but only one return var
  • if we don't want input or return variables we use void
