if

The if statement has a simple syntax:

if (a < b) { /* things to if a < b */ } /* .. */ if (a < b) { /* things to do if a < b */ } else { /* things to do if a >= b */ }

If the compound-statements only contain a single command, the curly brackets can be omitted. For example:

if (a < b) a = b; /* .. */ if (a < b) a = b; else a = a+1;
