在大字符串中删除所有指定小字符串居然有些难度，看来幼稚园也有挑战呀！

 

#include <stdio.h>

void del_c(char* s, char c) {
	char* ss;
	while(*s) {
		if(*s == c) {
			ss = s;
			while(*ss) {
				*ss = *(ss + 1);
				ss++;
			}
			*ss = '\0';
		} else {
			s++;
		}
	}	
}

int _strlen(char* s) {
	int len = 0;
	while(*s++) {
		len++;
	}
	return len;
}

int _strcmp(char* s0, char* s1) {
	int len0 = 0, len1 = _strlen(s0);
	if(len1 != _strlen(s1)) {
		return 0;
	} else {
		while((*s0) && (*s0++ == *s1++)) {
			len0++;
		}
		if(len0 == len1) {
			return 1;
		} else {
			return 0;
		}
	}
}

void _strcpy(char* s, char* d) {
	while(*s) {
		*d++ = *s++;
	}
	*d = '\0';
}

void _strcpy2(char* s, char* d, int len) {
	int i;
	for(i = 0; i < len; i++) {
		*d++ = *s++;
	}
	*d = '\0';
}

void del_s(char* fs, char* ss) {
	int len = _strlen(ss);
	char strtmp[0xff];
	char* tmp;
	while(*fs) {
//		printf("%s\n", fs);
		_strcpy2(fs, strtmp, len);
//		printf("%s\n", strtmp);
		if(_strcmp(ss, strtmp)) {
			tmp = fs;
			while(*tmp) {
				*tmp = *(tmp + len);
				tmp++;
			}
			*tmp = '\0';
		} else {
			fs++;
		}	
	}
}

int main(void) {
	char str[] = "my name# is li zhi qiang my name my nam name nams dd name#";
	printf("%s\n", str);
//	del_c(str, ' ');
//	printf("%s\n", str);
