if (num1 > num2)

result = num1;
else

We have kept max()along with main() and compiled the source code. While running the
final executable, it would produce the following result:

Max value is : 200

Function Arguments
If a function is to use arguments, it must declare variables that accept the values of the
arguments. These variables are called the formal parameters of the function.
Formal parameters behave like other local variables inside the function and are created
upon entry into the function and destroyed upon exit.
While calling a function, there are two ways in which arguments can be passed to a
function:

Call Type Description

Call by value This method copies the actual value of an argument into
the formal parameter of the function. In this case, changes made
to the parameter inside the function have no effect on the
argument.

Call by reference This method 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. This means that
changes made to the parameter affect the argument.
