Question
Chapter 4.6, Problem 25STE
Program Plan Intro
Description of Function:
Function has two parts that are called “function declaration” and “function definition”.
- The function declaration defines how the function is called.
- The function definition defines how the function computes the value it returns.
Parameters and arguments:
The parameter is used to denote to the variable as found in the definition of function and it is also called formal parameters.
The argument denotes to the actual input provided at function call and it is also called actual parameter.

Suppose you have two function definitions with the following declarations:double score(double time, double distance);int score(double points);Which function definition would be used in the following function call and why would it be the oneused?double x = 1.0;x = score(x, 2*x);
1. Write a function which takes one parameter int num, and prints out a countdown timer with minutes and seconds separated by a colon (:). It should print out one line for each second elapsed and then pause one second before printing out the next line. A few things to note:
- You can assume that calling the function usleep(1000000) makes the program pause for one second
- It should count down from num minutes:zero seconds to zero minutes:zero seconds
- Your function must have the following signature:
void timer(int num)
You do not need to demonstrate calling this function from main().
You don't need to format the output nicely; the below is acceptable output for calling this function when minutes is 10:
10:0
9:59
9:58
…
9:1
9:0
8:59
8:58
…
0:2
0:1
0:0
Consider the following function call:
draw_circle('red', 3)
What is the function name and what is the first argument passed to the function?
a.
The function name is draw_circle and the first argument is 3.
b.
You need to see the function definition to determine the function name and arguments.
c.
The function name is draw_circle, but you need to see the function definition to determine the arguments.
d.
The function name is draw_circle and the first argument is 'red'.
e.
The first argument is 'red', but you need to see the function definition to determine the function name.

- For this question you will design and implement a function that takes 5 arguments and produces 5 return values. This question is internally recognized as variant 0371. The 5 arguments must be of types int, int, bool, bool, and char (in that order), and they must be stored in parameter variables 'ham', 'bar', 'xyz', 'gzk', and 'foo', respectively. As a clarifying example, the second parameter - 'bar' - will be of type int. The function you create must perform the operations list below, in the specified order and exactly as they are described here. You are NOT permitted to simplify the operations. 1. create a new variable named 'ukr' that stores the result of increasing the 'ham' parameter by 42 2. if the conjunction of the 'xyz' parameter and the 'gzk' parameter has a value of True, multiply the value of the 'ham' parameter by a value of 29 and store the result back in 'ham' 3. negate the value of the 'xyz' parameter and store the result back in 'xyz' 4. decrease the value of the 'ham'…arrow_forwardWrite a function to divide variable ‘a’ with ‘b’.
