This means that when calling a function with parameters, what we have passed to the function were copies of their values but never the variables themselves. For example, suppose that we called our first function addition using the following code:</p> <blockquote> <blockquote><font color="#ff0000">int x=5, y=3, z;<br /> z = addition ( x , y );</font><br /> </blockquote></blockquote> <p>What we did in this case was to call to function addition passing the values of x and y, i.e. 5 and 3 respectively, but not the variables x and y themselves. <br /> </p>
