the execution continues after the statement.
Example:
while (get_rtcc()!=0)
putc('n');

do-while
do-while: Differs from while and for loop in that the termination
condition is checked at the bottom of the loop rather than at the
top and so the body of the loop is always executed at least once.
The syntax is:
do
statement
while (expr);
The statement is executed; the expr is evaluated. If true, the
same is repeated and when it becomes false the loop terminates.
Also See: Statements , While
for
For is also used as a loop/iteration statement.
The syntax is:
for (expr1;expr2;expr3)

The expressions are loop control statements. expr1 is the
initialization, expr2 is the termination check and expr3 is reinitialization.
Any of them can be omitted.
Example:
for (i=1;i
