Pass by reference vs. pass by value
List out differences between pass by reference and pass by valuePass by value always invokes / calls the function or returns a value that is based on the value. This value is passed as a constant or a variable with value.
Pass by reference always invokes / calls the function by passing the address or a pointer to a memory location which contains the value.
