Comparison between Looping Statements For …Next Statement Do …. While Statement It is one of the limited loop statements used when we want to repeat a code for specific number of time . It needs numeric variable (integer or decimal) to work as a counter with start value , end value and add or increment value . The statement 'Do while ... loop' is used to repeat a specific code for a several times of an unknown end, but based on a specific condition, so they are useful if you do not know the number of iterations emphatically. The repetitive code will be implemented (executed) as long as the counter variable is less than or equal the end value .The loop stops when the value of the counter exceeds the last value. The repetitive code will be implemented (executed) as long as the conditional expression is true. If the condition is not met for any reason, we get out of the iterative loop, and implement the code after the Loop if it exists. General syntax for this statement For Variable = Start To End Step Add Value Repetitive Code Next [Variable] Do While Conditional Expression Repetitive Code Loop
