字符串判等(方法也简单，简洁明了，注意：要使用isspace()函数，不然不能通过)

解题思路:

注意事项:

参考代码:

    #include<stdio.h>

    #include<ctype.h>

    #include<string.h>

    #include<stdlib.h>

        void RemoveSpaces(char* a, int len)

            {

                int j = 0;           //重新存放数组

                for (int k = 0; k < len; k++)        //遍历数组

                    {

                        if (!  isspace(a[k]))     //把不是空格的元素从头开始往前放

                        a[j++] = a[k];

                    }

                a[j] = '\0';

            }

        int main()

        {

            char a[10000], b[10000];

            gets(a);

            gets(b);

            int len_a = strlen(a);

            int len_b = strlen(b);

            RemoveSpaces(a, len_a);

            RemoveSpaces(b, len_b);

            for (int i = 0; i < len_a; i++)

                {

                    if (islower(a[i]))

                    a[i] = a[i] - 32;

                }

            for (int i = 0; i < len_b; i++)

                {

                    if (islower(b[i]))

                    b[i] = b[i] - 32;

                }

            if (strcmp(a, b) == 0)    printf("YES");

            else   printf("NO");

            return 0;

        }
