From time to time you may want to run some code not for the predetermined range of times but for just providing some situation stays legitimate. You may use a ‘though’ loop to do this.
The next line indicates that a perform named principal is becoming described. The leading functionality serves a special objective in C packages; the operate-time environment calls the key purpose to begin application execution.
