Difference between If and While Command (any language)?

Question

Whats the diffrence?

Answer 1

"If" will execute a block of code -- once -- if the given expression is true.

"While" will execute a block of code -- repeatedly -- as long as the expression is true at the top of the loop.

Answer 2

In an "if" statement, the "condition" is evaluated. If it is TRUE, then the code is executed once. That's it. Otherwise, the code is not executed.

In a "while" statement, the "condition" is evaluated. If it is TRUE, then the code is executed once. Repeat these steps until the "condition" becomes FALSE..
