The command “while” allows you to execute other commands until a certain criterion is met. It is very similar to if, because it also evaluates the truth of a statement, and while that truth is met, it executes the next command again and again and again, until the statement becomes false:
int i; i=0; while(i<100) i=i+1;
The above example might be simple but it illustrates a way to count to 100. Again like the if, in case you want to execute more than one command use {}:
int i; i=0; while(i<100){ i=i+1; printf("%i\n",i); }
The above code not only increments i a hundred times, it also prints it out.
