for Loop

// prototype
// for (expr1; expr2; expr3) { statement; }

Before executing, a for loop is initialized with a set of three expressions:

• expr1 initializes the counter for the loop. Unlike most languages, the counter cannot be declared in the for loop.
• expr2 is the condition for the loop's execution. If expr2 evaluates to FALSE the loop will break. This expression can be left blank to create an inifinate loop if you are planning on manually breaking out of the loop using the break statement.
• expr3 is the increment (or decrement) statement. This will be executed after all the statements in the loop code block are carried out, every time the loop is cycled through.

int i;
for (i = 0; i < 5; i++)
{
     // statements ...
     // this loop will cycle i as 0, 1, 2, 3, and 4
}
