A loop is a part of a program that repeats itself.
There are different types of loops, in this lesson we will just focus on the while loop.
The while loop tests a condition and if that condition is true it iterates.
Format:
while(condition){
do this;
}
There can be many reasons you would want to use a loop in your program. Most likely you will need a counter to track how many times the loop executes. You can either increment or decrement this value.
