WHILE - WHILE loops are very simple. The basic structure is while ( condition )  {  Code to execute while the condition is true  } The true represents a boolean expression which could be x == 1 or while ( x != 7 ) (x does not equal 7). It can be any combination of boolean statements that are legal. Even, (while x ==5 || v == 7) which says execute the code while x equals five or while v equals 7. Notice that a while loop is like a stripped-down version of a for loop-- it has no initialization or update section. However, an empty condition is not legal for a while loop as it is with a for loop. Example: #include <stdio.h> int main() { int x = 0; /* Don't forget to declare variables */ while ( x < 10 )  { /* While x is less than 10 */ printf( "%d\n", x ); x++; /* Update x so the condition can be met eventually */ } getchar(); }   This was another simple example, but it is longer than the above FOR loop.
