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…

Parameters are the value passed to a function when the function is called and Argument are the variable defined in the function definition. True or false

What is the difference between a formal parameter and an argument? Group of answer choices A function’s argument is referred to as the formal argument to distinguish it from the value that is passed in during the function call. The parameter is the passed value. A function’s parameter is referred to as the formal parameter to distinguish it from the value that is passed in during the function call. The argument is the passed value. A function’s parameter is used for passing by reference. The argument is used for passing by value. A function’s parameter is used for passing by value. The argument is used for passing by reference. They are identical but using different terms.
