What is the main difference between while and for loop ?

Answer 1

for loop includes it's own counter, condition and increment.

This makes it very useful when iterating through things.

consider the following while statement
int counter = 0;
while(condition == true) {
if(counter >= 3) }
condition = false;
}
else {
// do stuff
}
++counter;
}

compared to:
for(int counter = 0; counter >= 3; ++counter) {
// do stuff
}

Answer 2

Typically you would use a 'for loop' when you know how many times you want to repeat something and you're not usually checking a condition.

A while loop on the other hand is used when you don't know how many timed you need to repeat some and checks a condition to make the loop stop.
