This process goes on until the test expression is false. Difference between FOR and WHILE Loop With Example Key Difference: The FOR loop is often used when you usually know how many times you would like the program, which means it will run that program until the number of times is complete before it terminates itself. InitExpression: For loop starts with the initialization statement so, initialization of the counter variable should be done first (For example, @counter = 1 or @i = 1.). play_arrow. - This is used when we want to execute certain statements for a fixed number of times. Zero or more statement expressions from the following list, separated by commas: 2.1. assignmentstatement 2.2. invocation of a method 2.3. prefix or postfix increment expression, such as ++i or i++ 2.4. prefix or postfix decrement expression, such as --i or i-- 2.5… The for statement is in lower case. first two years of college and save thousands off your degree.
