C Programming Absolute Beginner's Guide (3rd Edition)

Tip

The word iteration is a fancy computer name for the cycle of a loop. Programmers

sometimes think they will keep their jobs if they use words that nobody else

understands.

The following program shows off continue nicely. The program contains a for loop that counts
from 1 to 10. If the loop variable contains an odd number, the message I'm rather odd...
prints, and the continue instructs C to ignore the rest of the loop body because it prints Even
up! for the even numbers that are left.

// File Chapter16ex2.c

/* This program loops through 10 numbers and prints a message that

varies whether the program is odd or even. It tests for odd and

if the number is odd, it prints the odd message and then starts

the next iteration of the loop using continue. Otherwise, it

prints the even message. */

#include <stdio.h>

main()

{

int i;

// Loops through the numbers 1 through 10

for (i = 1; i <= 10; i++)

{

if ((i%2) == 1) // Odd numbers have a remainder of 1

{

printf("I'm rather odd...\n");

// Will jump to the next iteration of the loop

continue;

}

printf("Even up!\n");

}

return 0;

}

Here is the program’s output:

I'm rather odd...

Even up!

I'm rather odd...
