'do' keyword in C

Question

do is a keyword in C and all I have seen is that it is only used with while. So my question is can do be used alone without while.

If yes how?

Answer 1

No. It cannot.

To be more precise, this is what the C standard has to say:

6.8.5 Iteration statements

Syntax

iteration-statement:

while ( expression ) statement
do statement while ( expression ) ;
for ( expressionopt ; expressionopt ; expressionopt ) statement
for ( declaration expressionopt ; expressionopt ) statement
