sscanf的应用

1.提取字符串

2.提取指定长度的字符串

3.提取指定字符为止的字符串

4.取仅包含指定字符集的字符串

5.取到指定字符集为止的字符串

#include <stdio.h>
int main()
{
    char str[512]={0};
    sscanf("123456","%s",str);
    printf("str=%s\n",str);
    sscanf("123456","%4s",str);
    printf("str=%s\n",str);
    sscanf("123456 abcdef","%[^ ]",str);
    printf("str=%s\n",str);
    sscanf("123456abcdefBCDEF","%[1-9a-z]",str);
    printf("str=%s\n",str);
    sscanf("123456abcdefBCDEF","%[^A-Z]",str);
    printf("str=%s\n",str);
    return 0;
}

运行结果如下:
