==Nest for loop inside do while loop==

<source lang="cpp">#include <stdio.h>
int main()
{
int start = 10;
long delay = 1000;

do
{
printf(" %d\n",start);
start--;
for(delay=0;delay<100000;delay++); /* delay loop */
}
while(start>0);

printf("Zero!\nBlast off!\n");
return(0);
}</source>
<pre class=codeResult>10

Zero!
Blast off!</pre>

==Read number in a range==

<source lang="cpp">#include <stdio.h>
int main(){

printf("Please enter the number to start\n");
printf("the countdown (1 to 100):");
int start;
scanf("%d",&start);
do {
printf("%d",start);
}while(start<1 || start>100);
}</source>
<pre class=codeResult>Please enter the number to start
the countdown (1 to 100):12
12</pre>

==Reversing the digits: do while loop==

<source lang="cpp">#include <stdio.h>
int main(void)
{
int number = 123;
int rightMostNumber = 0;
int temp = 0;
temp = number;
do
{
rightMostNumber = 10*rightMostNumber + temp % 10;
temp = temp/10;
} while (temp);
printf ("\nThe number %d reversed is %d\n", number, rightMostNumber );
return 0;
}</source>
<pre class=codeResult>The number 123 reversed is 321</pre>

==The do...while loop==

<OL><LI>The do...while loop checks the conditional expression only after the repetition part is executed.</LI><LI>The do...while loop is used when you want to execute the loop body at least once.</LI></OL>
<p>The general form of the do...while loop is</p>

<source lang="cpp">do {
repetition part;
} while (expr);</source>
