Difference Between For and While Loop

For Loop
A loop is a fixed repetition. It will run the given number of times no matter how the body of for loop code changes the values of the variables.

If you have a constant (eg. Max Students), you can run the For Loop for that many times. You can change the value of the constant. Every year you can change the value of Max Students.

The counter value increases or decreases depending upon the for loop min, max, incremented or decremented values automatically as stated per requirement - no separate statement is made within the body of for loop.

A separate variable is needed most times to run a For Loop.

A For Loop can also start with a maximum value and decrease each time the body of the loop is executed.

While Loop
While loop can have various conditions and they can be joined (AND OR). The control enters the loop body only when the condition is met. If the condition is not met, the control goes to the statement following the end of the while loop body. A statement within the while loop changes the criteria and that actually moves the control out and to the statements that are following the end of while loop body.
