Difference Between Parameter and Argument

Parameter

Parameter is a variable in the declaration of function.

int add(int x,int y)

{

return x+y;

}

In this example int x,int y are parameters.

Argument

Argument is the actual value of this variable that gets passed to function.

E.g.

int result;

result=add(1,2);

In this example 1,2 are arguments.
