C++ Programming: From Problem Analysis To Program Design, Loose-leaf Version
- 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. (11)arrow_forwardCode using c++ 3. 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_forwardc++, print the outputarrow_forward
- Need 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_forwardC++ 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_forward
- C++ Programming Exercise: When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first month's interest on $1,000 is 1000 X 0.006 = 6. Becuase the payment is $25 and the interest of the first month is $6, the payment toward the principal amount is 25-6 = 19. This means after making the first payment, the loan amount is 1,000-19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 X 0.006 = 5.886,…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_forwardExplanation: Default arguments should always be declared at the rightmost side of the parameter list but the above function has a normal variable at the rightmost side which is a syntax error, therefore the function gives an error. 1. #include int fun(int=0, int = 0); int main() { cout << fun(5); return 0; } int fun(int x, int y) { return (x+y); } а) -5 b) 0 c) 10 d) 5 2. int main() { int a=10; int b,c; b =a++; c = a; cout<arrow_forwardc++arrow_forwardModule/Week 7 ASSIGNMENT (ARRAYS)Use functional decomposition to write a C++ program that asks the user to enter his or her weight and the name of a planet. Use an enumerated type called planetType to represent the planets and use a switch statement that takes as its condition a planetType variable. The program, via the switch statement, then outputs how much the user would weigh on that planet. The following table gives the factor by which the weight must be multiplied for each planet.Your program must have the following functions in it: GetUserInput(),ConvertInputToPlanetType(), and OutputWeight() (your switch statement must be in OutputWeight()). I will let you determine what each function’s parameters and return types should be. The program will output an error message if the user does not type a correct planet name. The prompt and the error message will make it clear to the user how a planet name mustbe entered.Use proper formatting and appropriate comments in your code.
