与C编程相关的问题(入门) [英] C programming related problem(beginner)

问题描述

str [j]！=''\ 0''
是什么意思?
以及如何通过比较字符串和打印最终结果来删除重复字符.
如果str1 = A，B，C，D
和str2 = A，C，E，F，B

str[j] != ''\0''
what it means?
and how to remove duplicate character by comparing both string and print final result.
if str1=A,B,C,D
and str2=A,C,E,F,B

推荐答案

以下代码行检查当前字符是否为空终止符.空终止符表示字符串结尾.

The following line of code checks to see if the current character is the null terminator. A null terminator indicated the End Of String.

str[j] != '\0'

通常在while循环中使用它来检查是否已达到字符串的最后一个字符.如果它是最后一个字符，则循环将终止.

我假设您想删除两个字符串共有的字符.您可以这样做:

This is usually used in a while loop to check if the last charecter of the string has been reached. If it is the last char, the loop will terminate.

I assume you want to remove characters common to both strings. You could do this:

int i=0, j=0, index=0;
char tmp;

while(str1[i] != '\0')
{
tmp = str[i];
    while(str2[j] != '\0')
    { 
         if(  tmp != str2[j] ) 
             { 
                  
                result[pointer] = tmp;     // Copy the non common charecter to result array
                pointer++;                 // Increment pointer

             }   
     j++;
    }
i++;
}
