Question

What happens if the condition in a while loop is initially false? Explain and differentiate

between while and do while statement in ‘C’ language.

Answer 1

The execution flow won't go through while loop body, i.e. everything inside the curly brackets { ... } won't be executed. As for do { ... } while(false), the content in curly bracket wil be executed once before reading condition while (...). After that the loop content won't be executed anymore.
