Chapter 2.7, Problem 2.12CP
A) From the table 2-6:
Program Plan Intro
Data types:
The variables use data-type during their declaration.
- The data-type is used to determine the size of memory allocated. Here, the compiler allots the memory.
- All data-type needs different size of memory.
Some of the data-types are:
- Integer
- Boolean
- Character
- Double
- Floating point

- What do you understand by local and global scope of variables? How can you access a global variable inside the function, if function has a variable with same name.arrow_forwardComplete the function movie_cost, which takes three parameters: age, permission and rating. age is an integer containing a person's age in years; permission is a Boolean that indicates whether a person has parental permission to see a particular move; and rating is one of G, PG, PG-13, or R. The function returns the cost of movie theater admission for the person according to the following rules, which are listed in order of decreasing precedence/priority: Nobody under the age of 10 may view an R-rated movie. • You must be 17 years old or have parental permission to view an R-rated movie. • You must be at least 13 years old or have parental permission to view a PG-13-rated movie. Prices: • Adult tickets (age greater than or equal to 16) are $15 each. • Child tickets (age less than 16) are $10 each. • If the person is not allowed to see the move, return o.

One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function. Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.

- Define Named constant.arrow_forwardDefine a function named change_values that takes four integers as parameters and swaps or changes them based on a set of rules. Your Change Function should follow the following rules in the following order: 1. If the second value is an odd number, then it should be swapped with the first number. 2. If the third value is a power of two, then it should be swapped with the fourth value. 3. If the summation of the current values 1 to 3rd (after the above two rules are applied) is equal to the fourth value, then the fourth value should be set to the first value. Then write a Main program that reads four integers from standard input, calls function change_values() to swap the values, and prints the swapped values on a single line separated with spaces. Example Input: 1 3 4 0 Example Output: 3 1 0 3arrow_forwardProgramming Language: C++ 3. Which of the following are true for static variables but not for other variables? Select one or more: a.

They can be used as arguments when calling a function d. They retain the value stored in them even after the function where they are defined returns e. They can be defined and initialized on the same line.arrow_forward
