How does a computer store variables passed by value and variabled passed by reference?

What will be an ideal response?

When you pass a variable by value, the computer uses the data type and name of its corresponding formal parameter to create a separate memory location in which to store the value. When you pass a variable by reference, on the other hand, the computer locates the variable in memory and then assigns the name of its corresponding formal parameter to the memory location. When you pass a variable by reference, the variable will have two names: one assigned by the calling function and the other assigned by the receiving function. Void functions use variables that are passed by reference to send information back to the calling function. Value-returning functions, on the other hand, send information back to the calling function through their return value.
