In C++, the & symbol after the type in the parameter list does what?
|
The & symbol alerts the compiler that the parameter is call by reference. |
||
|
The & symbol alerts the compiler that the parameter is call by value. |
||
|
The & symbol alerts the compiler that the parameter is a placeholder. |
||
|
The & symbol alerts the compiler to swap the actual and formal parameter. |

In C++, the & symbol after the type in the parameter list does what?
The & symbol alerts the compiler that the parameter is call by reference.
symbol & is used in C++ as an address operator.If you take the address of a reference, it returns the address of its target. We can use & for call by refference.

What is the key difference between an array and a symbol table? Assume you have a bunch of objects containing information about different SER classes and need to store their data somewhere. You could use their course number as a key and then store them into either an array or symbol table - which would be better if you wanted to quickly print out all of the classes? Explain. Show...

Write a method named factorial that accepts an integer n as a parameter and returns the factorial of n, or n!. A factorial of an integer is defined as the product of all integers from 1 through that integer inclusive. For example, the call of factorial(4) should return 1 2 3 4, or 24. The factorial of 0 and 1 are defined to be 1. You may assume that the value passed is non-negative and that its factorial can fit...

python: def functionSolver(function: callable)->str You will be given a function as a parameter, the function you are given only accepts two number parameters and produces a float value. It is your job to figure out what mathematical operation the function you are given is performing by passing it many different parameters. The possible operations the function can perform are: add, subtract, multiply, and divide. The given function will only perform a single operation, it will not change after consecutive invocations....
