⚡Call by value method copies the value of an argument into the formal parameter of that function. Therefore, changes made to the parameter of the main function do not affect the argument.
⚡Call by reference method copies the address of an argument into the formal parameter. In this method, the address is used to access the actual argument used in the function call. It means that changes made in the parameter alter the passing argument.

📌In the Call by value method original value is not modified, whereas in the Call by reference method, the original value is modified.

📌In Call by value, a copy of the variable is passed, whereas in Call by reference, a variable itself is passed.

📌In Call by value, actual and formal arguments will be created in different memory locations, whereas in Call by reference, actual and formal arguments will be created in the same memory location.

📌Call by Value variables is passed using a straightforward method, whereas Call by Reference pointers are required to store the address of variables.
