if statements allows for human-readable, logical branches in code. While usually not the only control statements in programming languages, they provide both a simple and a powerful method to allow code to divert off of a preset path.

The "if" function evaluates an expression to either true or false. (In most systems, a value of zero equates to false, and any non-zero value to true.) If the expression is true, then the following command(s) is/are performed. If the expression is false, then no action is taken.

For example:

  • if (1+1=2) then print "Hey, that was easy!"
  • if (2+2=5) then print "This will never happen."
