For Loop:
A for loop is a programming language statement which allows code to be repeatedly executed.
Syntax:
for (condition) {
statements;
}
Example 1:
We want a word to be printed 5 times.
- “i++” means post increment.
- “n” means newline.
Result:

While Loop:
A while loop is a control flow statement that allows a code to be executed over and over until a specific situation is met, which is set up in the while statement.
note:
You don’t have to write an endless loop, it will tie up computer resources.
Syntax:
while (condition) {
statements;
}
Example:
In this example the program asks the user repeatedly to enter an even number, while the number entered is an odd number.
- “n%2!=0″ means that the reminder of the division of n by 2, must not be 0.
Result:
