How to realize string inversion in C language

This article mainly introduces how to achieve string inversion in C language, which is very detailed and has a certain reference value. Friends who are interested must read it!

Code implementation # include # include # define MAX_LENGTH 50 / / maximum length char * String_Invertion (char * str); int main () {char string [Max _ LENGTH]; printf ("Please enter a string\ n"); scanf ("% s", string); String_Invertion (string); printf ("inverted string is% s\ n", string); return 0 } / * @ brief string inversion function * @ param str target string * @ return inverted string (str) * / char * String_Invertion (char * str) {if (str = = NULL) return NULL; int len = strlen (str); int I = 0; for (I = 0; I < len / 2) Replace len/2 times {/ * (bitwise) XOR exchange, other exchange methods refer to day27 * / str [I] = str [I] ^ str [len-1-I]; str [len-1-I] = str [I] ^ str [len-1-I]; str [I] = str [I] ^ str [len-1-I];} return str;}
