This article mainly introduces what is the only function of a c program, which has certain reference value and can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

A c program has one and only one main function (main () function). A C language source program can consist of one or more source files. No matter how many files a source program consists of, there is one and only one main function, that is, the main function.

The main function is the entry function of the C program, that is, the execution of the program starts from the main function, and the transfer of other functions is also called directly or indirectly in the main function.

The most important feature of C program is that all programs are assembled with functions. Main () is called the main function and is the entry into which all programs run. The rest of the functions are called by the main () function or other general functions with or without parameters. If the function is called with parameters, the parameters are passed when the function is called.

Int main (void) / / Integer type main function (untyped) {... y1=f1 (x1line x2); / / assignment process. F1 (int aline int b) / / F1 (integer type a, integer type b) {/ / sample code .Y2 = f2 (x3Powerx4) / / assignment process / / sample code} f2 (int mreint n) / / f2 (integer type m, integer type n) {/ / sample code} Thank you for reading this article carefully. I hope the editor will share the content of the only function of a c program that is helpful to everyone. At the same time, I also hope that you will support us, pay attention to the industry information channel, and find out if you encounter problems. Detailed solutions are waiting for you to learn!
