Use of sscanf () and sprintf () in C language

#include <stdio.h>void main (void) {    char * cgistr = ' | ip=192.168.1.78| port=5678| dbname=haha| user=hehe| Pwd=123456| ";    Char cbusip[16]= "";    int nport = 0;    Char cdbname[64] = "";    Char cuser[64] = "";    Char cpwd[64] = "";    Char cquestcmd[16]= "";    SSCANF (Cgistr, "| ip=%[^|]| port=%d| dbname=%[^|]| user=%[^|]| Pwd=%[^|]| ", Cbusip, &nport, Cdbname, Cuser, CPWD);    printf (CBUSIP);    printf ("\ n");    sprintf (Cquestcmd, "Hget%s_infor OWner", cdbname);    printf (cquestcmd);    printf ("\ n");}

Console output:

192.168.1.78
Hget haha_infor OWner
It's a sight to see.

sscanf (parameter 1, parameter 2, Parameter 3 ...) is to assign the desired field in Parameter 1 to parameter 3 by the form of parameter 2 ....

sprintf (parameter 1, parameter 2, Parameter 3 ...) is the parameter 3 ... The field is stitched to parameter 1 in the form of parameter 2.

"%n[a-z]" reads up to n characters and stops if a non-a-Z character is encountered
"%[^=]" reads any number of characters until it encounters "=" Stop
"%n[^=" reads up to n characters before the "=" sign
