Algorithm to delete a given character

During the interview, the interviewer asked me to write an algorithm title: Given a string and a character, the deletion string contains the same character as this character.

Algorithm 1:

1#include <stdio.h>2 3 voidDelchar (Char* STR,Charp) {4     inti =0;5     intj =0;6      while(Str[j]! =NULL) {7         if(Str[j] = =p)8J + +;9         Else{TenStr[i] =Str[j]; Onei++; AJ + +; -         } -     } theStr[i] =' /'; - } -  - intMain () { +     Chartest[ -] ="www.baidu.com"; -Delchar (Test,'W'); + puts (test); A //Free (s); at     return 0; -}

Algorithm 2: (Dynamic allocation of space)

1#include <stdio.h>2#include <string.h>3#include <malloc.h>4 5 Char* Delchar (Char* STR,Charx) {6     intLen =strlen (str);7     if(str = =NULL)8         returnNULL;9     Ten     Char*p = (Char*)malloc(Len +1);  One     Char*q =p; A      while(*str! =' /'){ -         if(*str = =x) -str++; the         Else { -*p++ = *str; -str++; -         } +     } -*p =' /'; +     returnQ; A } at  - intMain () { -     Chartest[ -] ="www.baidu.com"; -     Char*s = Delchar (test,'W'); - puts (s); -      Free(s); in     return 0; -}
