In call by reference, original value is changed or modified because we pass reference (address). Here, address of the value is passed in the function, so actual and formal arguments shares the same address space. Hence, any value changed inside the function, is reflected inside as well as outside the function.

|No.||Call by value|
|1||A copy of the value is passed into the function|
|2||Changes made inside the function is limited to the function only. The values of the actual parameters do not change by changing the formal parameters.|

The call by reference method of passing arguments to a function copies the address of an argument into the formal parameter. Inside the function, the address is used to access the actual argument used in the call. It means the changes made to the parameter affect the passed argument.
