The C language itself does not have a function to find a string and return an index, although it is easier to say that you can get an index by writing a lookup function.C language has a strchr function to find the first position of the character, the key is this function, if used skillfully, you can also get the index of the found string1 char *str_1 = "wtwq211"; 2 char *str_2 = STRCHR (str_1, ' Q '); 3 printf ("%s\n", str_2); 4 5 int index= Str_2-str_1;6 printf ("%c\n", Str_

since future projects will use Spring boot technology as the theme, these days have tried Springboot+dubbo to complete the layering of business architectures, this article mainly records the Dubbo null pointer problems encountered during SPRINGBOOT construction. First, we recommend that you have a channel to this problem and take a look at this articleHttp://www.oschina.net/question/1011127_144093?fromerr=7pRd3NKvAlthough this article does not solve the problem of springboot configuration, but t

Very early to study Ajax through the JSON way to go back to the list to the foreground display, today finally made out, put the code to share to everyone The Ajax JSON method requires a jar package, which is shared from the attachment to everyone.

#include The C language writes the string manipulation function strrchr, finds the last occurrence of the target character in a string, and returns a pointer to this position.
