If statement

The if clause is useful in that allows bifurcations : true and false tracks. If the if expression evaluates to non-zero(1, 20, -5, 0.3202), the true track is chosen by the computer's processor. If the if expression evaluates to zero(0), the false track is chosen.

Pseudo code is firstly used, then the actual C syntax replaces the pseudo code, and finally the application is built and run.
