C语言新人求助

输入一个字符串，将其中的除了0之外的数字字符组成一个数字。
最好用到指针。
麻烦各位大神了

[小灸舞]

#include<stdio.h>
void main() 
{ 
	char str[128] = {0};
	char buffer[128] = {0};
    char *p = str, *q = buffer;
	printf("请输入字符串:");
	scanf("%s", str);
	while(*p != '\0')
	{
		if(*p >= '1' && *p <= '9')
			*q++ = *p;
		*p++;
	}
	*q = '\0';
	printf("转换后结果为:%s\n", buffer);
}

字符串转化为整数 http://blog.csdn.net/zhangxiangdavaid/article/details/25245125

#include <stdlib.h> #include <stdio.h> int _tmain(int argc, _TCHAR* argv[]) { char buff[1024] = {0}; scanf("%s", buff); //输入102.01s10后回车 for (int i = 0; i < 1024; ++i) { if (buff[i] == '0') { memmove(buff + i, buff + i + 1, 1024 - i - 1); } } double value = strtod(buff, nullptr); //value = 12.100000000000000 return 0; }

#include <stdlib.h>
#include <stdio.h>

int _tmain(int argc, _TCHAR* argv[])
{
	char buff[1024] = {0};
	scanf("%s", buff);
	//输入102.01s10后回车

	for (int i = 0; i < 1024; ++i)
	{
		if (buff[i] == '0')
		{
			memmove(buff + i, buff + i + 1, 1024 - i - 1);
		}
	}

	double value = strtod(buff, nullptr);
	//value = 12.100000000000000
	return 0;
}

这样好看点
