- Why would you want to use a return statement in a void function, you may wonder.If you are writing a function that accepts an argument and you want to make sure the function cannot change the value of the argument, what should you do?You might be wondering why you'd want to utilise a return statement in a void function.
- In a void function, how would you utilise a return statement?A. Function calling another function You have already seen a function that has called another function, but you may not have paid close attention to it. In order to call a programmer-defined function inside another programmer-defined function, you need to have the declaration of the function that is being called before the declaration of the calling function. In this program you will write a function of void return type named compare that accepts an integer parameter named guess. This function will compare the value of guess with a seeded randomly generated integer between 1 to 100, inclusive, and let the user know what the random number was as well as whether the guess was larger than, smaller than or equal to the random number. NOTE THAT: You will NOT generate a random number inside the compare function. Rather, you will write another function named getRandom of int return type to do it. You will need to call getRandom from compare, no parameters are necessary. Inside your main…Playing with Functions: Write a Javascript program to check if the argument passed to any function is a function type or not. I.e. Create a function check which takes a argument and check if that argument is a function or not.
- How does a value-returning function differ from the void functions?1. What is this paramters that are only accessible in the body of the function, like all variables used in the function? 2. What is the part of the program that creates function? 3. It performs operations like union, difference and intersectiondone in c++ Program Specifications: Write a program that asks for a user's name and age, finds the ticket price based on the age, and prints out the user's name, age, and ticket price. 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.
