The primary functions of the respiratory system is to: -supply oxygen to the blood -ventilate the lungs -excrete water vapour and carbon dioxide -maintain the pH (percent hydrogen) of blood -conduct respiration -regulate gas exchange -release energy
The main function is the entry point for the application. Each program written in C or C++ will start at the first line in the main function, and cease execution once the main function returns control to the operating system (either via a return keyword in the main function, an exit(3) function call, or by "running off" the end of the main function). A program will not compile if it is missing the main function. Some variants of C++ have an alternate entry point (including those written for Microsoft Windows).
