Overview
A "while" loop performs a set of commands for each iteration of the loop.
Usage
while (condition)
Examples
int i;
i = 0;
while( i < 10 ) {
printf("This is a test. Loop %s\n", i) ;
i = i + 1;
} ;
This example will iterate the loop, printing the "This is a test. Loop n" message 9 times.
Results
This is a test. Loop 0
This is a test. Loop 1
This is a test. Loop 2
This is a test. Loop 3
This is a test. Loop 4
This is a test. Loop 5
This is a test. Loop 6
This is a test. Loop 7
This is a test. Loop 8
This is a test. Loop 9
