C Program To Swap Two Numbers using Function

C Program To Swap Two Numbers using Function

Lets write a C program to swap 2 numbers using function/method.

In today's video tutorial we'll be showing you the concept of Call By the function

When we call a function and pass the actual value
it’s called as Call by Value method.
If we pass the reference or the address of the variable while calling the function,
then it’s called Call by Reference.



What is Function Call By value?
When we pass the actual parameters while calling
a function then this is known as function call by value.
In this case the values of actual parameters are copied to
the formal parameters. Thus operations performed on the
formal parameters don’t reflect in the actual parameters.
