Question
Chapter 6, Problem 3D
Program Plan Intro
Parameter:
- A parameter is a special kind of variable.
- It is used in a subroutine to refer to one of the pieces of data provided as input to the subroutine.
- Parameter is also called Formal Argument
Explanation of Solution
Difference between formal and actual parameter: ?
Formal parameter | Actual parameter |
A function’s name preceded by “def” and continued with parameters in parentheses are called formal parameters. | The values passed into a function each time the function is called in a program are called Actual parameters... |
Explanation of Solution
Similarities and Differences between parameters and variables: ?
- The parameter becomes a variable when you pass it into a function.
- If the user makes a call to the function type, then the user can pass in not just a variable, but things like a string literal ("line"), an integer (101), a float (1...
