C++ Programming: From Problem Analysis to Program Design
- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls.

From Person to People by CodeChum Admin Now that we have created a Person, it's time to create more Person and this tech universe shall be filled with people! Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age and character value for its gender. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. In the main() function, there's a pre-created array of 5 Persons. Your task is to ask the user for the values of the age and gender of these Persons. Then, once you've set their ages and genders, call the displayPerson() function and pass them one by one. Input 1. A series of ages and genders of the 5 Persons Output Person·#1 Enter·Person's·age:·24 Enter·Person's·gender:·M Person·#2 Enter·Person's·age:·21 Enter·Person's·gender:·F Person·#3 Enter·Person's·age:·22 Enter·Person's·gender:·F Person·#4…arrow_forward
- c++, print the outputarrow_forwardNeed Code in C++ Write a program that uses a structure named MovieData to store the following information about a movie: Title Director Year Released Running Time (in minutes) The program should create two MovieData variables, store values in their members, and pass each one, in turn, to a function that displays the information about the movie in a clearly formatted manner.arrow_forwardC++ Functions provide a means to modularize applications Write a function called "Calculate" takes two double arguments returns a double result For example, the following is a function that takes a single "double" argument and returns a "double" result double squareArea(double side){ double lArea; lArea = side * side; return lArea;}arrow_forward
- C++ printSmaller is a function that accepts two int parameters and returns no value. It will print the value of the smaller one parameters. The function protoype is as follows: void printSmaller(int num1, int num2); write the statments to read two integers and call this function to display the smaller one.arrow_forwardFill-in-the-Blank When a function uses a mixture of parameters with and without default arguments, the parameters with default arguments must be defined _________.arrow_forwardC++ 1 year = 15 months 1 month = 30 days write a function that takes an int parameter that represents the number of days, and converts the number of days to years, months, and days and returns this information in a struct Go to Se So for example, it will convert 800 days into a struct that Activa represents one year, 11 months, and 20 daysarrow_forward

The program must define the following 3 functions and call them in the main function. Create a function called getName that takes in no arguments and returns the name of the user. Create a function called getAge that takes in the argument age and uses pass-by-reference to set the age of the user. Ensure that the user cannot put in an age that is negative or greater than 100. Create a function called printTicket that takes in the user's name and age and does the following ○ If they are less than or equal to 13 years old set ticket_Price to 9.99. ○ If their age is greater than 13 and less than 65, set ticket_Price to 19.99. ○ If their age is greater than or equal to 65, set ticket_Price to 12.99. ○ Output to the console the user's name, age and ticket price.arrow_forwardC++ programarrow_forward
