Question 3

For loop?

Answer 3

They are used when you know exactly how many times you want to loop through a block of code.

for (stat1; stat2; stat3) 〔
// code to run
〕

Stat1 is executed on e before the execution of the code block in brackets.

Stat2 defines the condition for executing the block.(which is why you may be using the for loop in the first place, since you know this to be relatively exact)

Stat3 is executed every time after the code block has been executed.
