getchar解决问题

解题思路:
先输入再用字符比较
注意事项:i与j的比较

参考代码:

#include <stdio.h>

int main()

{

int word = 0, number = 0, tab = 0, otherword = 0,i=0;

char ch[200];

ch[0] = getchar();

while(ch[i] != '\n')

{

i++;

ch[i] = getchar();

}

int j;

for (j = 0; j < i; j++)

{

if ((ch[j] <= 122 && ch[j] >= 97)||(ch[j] <= 90 && ch[j] >= 65))

word++;

else if (ch[j] <=57 && ch[j] >=48)

number++;

else if (ch[j] == ' ')

tab++;

else

otherword++;

}

printf("%d %d %d %d", word, number, tab, otherword);

return 0;

}
