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. (11)arrow_forwardAdmission Write a C++ program that: Define a void function named Admission() with two parameters. The function accepts two arguments: a student’s high school grade point average (for example, GPA is 3.2) and an admission test score (for example, 83). The function then displays a message “Accepted” if the student has any of the following: A GPA of 3.6 or above and an admission test score of at least 60. A GPA of 3.0 or above and an admission test score of at least 70. A GPA of 2.6 or above and an admission test score of at least 80. A GPA of 2.0 or above and an admission test score of at least 90. If the student does not meet any of the qualifications, the function should display a message “Rejected”. //for example, here is the function header: void admission (double gpa, int score) Write a function prototype statement for function Admission before the main function, and add function definition after the main function in the program. In the main function, prompts user to enter a…arrow_forwardmy_func is a function as follows. What is the value of a at the end of the code beneath? function a = my_func (a) a = a + 1; end a = 0; for i = 1:3 my func (a); end a = my_func (a);arrow_forward
- Code 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_forward# Python 3 def printFunction(num1, num2): num3 = num1 + num2 return num3print(num3) Explanation: Here, num3 is the local variable that is defined in the scope of the function and when it is used outside the function, an error occurs. Print(num3) is the statement which is outside the scope of the function. So, when this statement is executed, there is no variable named num3 to be printed, so it gives an error. The error that occurs is : NameError: name 'num3' is not defined Construct a function that takes an argument. Give the function parameter a unique name. Show what happens when you try to use that parameter name outside the function. Explain the results. Show what happens when a variable defined outside a function has the same name as a local variable inside a function. Explain what happens to the value of each variable as the program runs.arrow_forward1 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 So for example, it will convert 800 days into a struct that represents one year, 11 months, and 20 daysarrow_forward
- JAVA CODE PLEASE Functions With No Parameters and Return Values Practice ll by CodeChum Admin Create a program that has a global integer variable assigned to a value of 1. Then, create a new function named increment that increments the global variable. In the main function, if the current value of the global variable is divisible by 3, print “Cody!”. Otherwise, print the value of that global variable. Repeatedly call the increment function until the value of the global variable is greater than 15. Output Multiple lines containing a string or an integer 1 2 Cody! 4 5 Cody! 7 8 Cody! 10 11 Cody! 13 14 Cody!
