练习12—统计特定字符个数

#include <stdio.h>

int main()
{
	char input;									 
	int word = 0, num = 0, blank = 0, other = 0; 
	printf("please enter the character and press enter to confirm:");
	for (; (input = getchar()) != '\n';) //注意括号位置
	{
		if ((input >= 'a' && input <= 'z') || (input >= 'A' && input <= 'Z'))
			word++;
		else if (input >= '0' && input <= '9')
			num++;
		else if (input == ' ')
			blank++;
		else
			other++;
	}
	printf("word=%d,num=%d,blank=%d,other=%d\n", word, num, blank, other);
	return 0;
}
