What to do (keyword) C ++?

Question

I never knew there was a keyword, do, in C ++!
what is it?

Answer 1

This is the loop:

do {
...
} while(someCondition);

Answer 2

Good thing it is used with while keyword:

do {
   ...
} while(foo)

Unlike a loop for a do-while loop, it always runs at least once .

Also note that do {} while (0) is a commonly used idiom in the Linux kernel, see this faq for details.

Answer 3

. , . ,

do {
/* Code will always be executed at least once */
/* something needed to be done once or more times */
} while ( /* not done /* )

as

while( /* not done */) {
 /* this code may never be executed */
}
