An example Analysis of the Parameter problem of main () function in C language

This article mainly introduces the C language main () function parameters of the example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor with you to understand.

# includevoid main (int argc, char* argv []) {while (argc > 1) {+ + argv; printf ("% s\ n", argv);-- argc;}}

# include#includevoid main (int argc, char* argv []) {int i; printf ("The number of string is:% d\ n", argc-1); for (I = 1; I

< argc; i++) { printf("the string %d is:%s\n", i, argv[i]); }}

# includevoid main (void) {const char* str = "Welcome to Fishc.com!\ n\ n"; / / this statement means: declare a pointer variable named str, / / it points to a character variable, and initialize str to point to the string / / "Welcome to Fishc.com!\ n\ n" # if (0) str [0] ='w' # endif str = "I love Fisfc.com!\ n\ n"; printf ("\ n\ n% s", str);}

# includevoid main (void) {char* const str = "Welcome to Fishc.com!\ n\ n"; / / the constant pointer is a fixed pointer and its value cannot be changed, but the data it refers to can be changed str [0] = 'wishful positioning if (0) str = "I love Fisfc.com!\ n\ n"; # endif printf ("\ n\ n% s", str);}

There's a problem
