c语言怎么删除字符串中相同字符?
c语言去除字符串中的重复字符
比如输入12eerer,输出12er
#include<stdio.h> #include<string.h> #define MAX 100 int main() { char str[MAX]; char c; int strlen = 0; int i,j,k; scanf("%s",&str);//连续输入字符串 for(i = 0;str[i] != '\0';i++); strlen = i; for(i = 0;i <= strlen - 1;i ++) { for(j = i + 1;j <= strlen - 1;j ++) { if(str[i] == str[j]) { for(k = j;k <= strlen - 1;k ++) { str[k]=str[k + 1]; } strlen --; j --;//避免出现多个相同字符连在一起时出错的问题 } } } str[strlen] = '\0'; printf("%s",&str); return 0; }
