凤尾竹和散尾葵的区别:求助，由键盘输入一个字符串和一个字符，要求从该字符串中删除所指定的字符

#include <string.h>

int main()
{
char c;
char s1[],s2[];
//**********这里是一些初始化的地方，比如说前面的语句等等*******************
//**********假设原来的字符串是s1，新字符串是s2，需要删除的字符是c，那么****

int i;
s2={""};
for (i=0;i<strlen(s1);i++)
{
if (s1[i]!=c)
strcat(s2,s1[i]);
}

//**********此时，s2里面就是删除之后的字符串了***********

return 0;
}

说明白一点

main()
{char str[11]="how are you";
int *p;
p=str;
for(;p>=&str[2]&&p<=&str[11];p++)*p=*(p-1);
printf("%s%",str);}

如果错了,对我说,我再看看有什么错误

用链表给你作的 （其实是很早以前作的几个东西剪切一些功能那到这里的一个产物）给你调试过了 有问题可以找我 gabmyd@126.com
