No. If the loop condition is not satisfied then the loop would not be executed even once. while(condition) { ..... /statements ..... } here,when the condition is true then the statements will be executed. Otherwise they would be skipped without being executed. Only for do.. while loops this execution at least once holds good.

It is required for an able Muslim to perform hajj once in their lifetime; if you perform it multiple times, then that's a voluntary act of worship.It was narrated from Ibn 'Abbaas that al-Aqra' ibn Haabis asked the Prophet (peace and blessings of Allaah be upon him): "O Messenger of Allaah, is Hajj every year or just once?" He said: "It is only once, and whoever does more than that, it is a voluntary (act of worship)."

A do-while loop always executes at least once, and works like this: do { //code, such as incrementing a value, printing text, etc. } while (expressionToEvaluate); a perfect example of this would be something like: <code> int i = 10; int counter = 0; do { counter+=i; i--; } while (i > 0); </code>
