那个 初学…c,该如何处理

那个 初学…………c
就是输入字符统计那个 谁帮帮我啊……//
#include<stdio.h>
main()
{
char c;
int ncount,ccount,scount,ocount;
  ncount = ccount = scount = ocount = 0;

for(;(c = getchar()) <= EOF;)
{

if ((c>='A'&& c<='Z')||(c>='a' && c<='z'))
ccount++;
else if((c>=0 && c<=9))
ncount++;
else if(c == ' ')
scount++;
else
ocount++;
}

printf("the digit of character is:%d\n",ccount);
printf("the digit of number is:%d\n",ncount);
printf("the digit of space is:%d\n",scount);
printf("the digit of other element is:%d\n",ocount);
}

[解决办法]

C/C++ code

#include<stdio.h>main(){    char c;    int ncount,ccount,scount,ocount;    ncount = ccount = scount = ocount = 0;    while((c = getchar()) !=EOF)    {            fflush(stdin);         if ((c>='A'&& c<='Z')||(c>='a' && c<='z'))            ccount++;        else if((c>=0 && c<=9))            ncount++;        else if(c == ' ')            scount++;        else            ocount++;    }    printf("the digit of character is:%d\n",ccount);    printf("the digit of number is:%d\n",ncount);    printf("the digit of space is:%d\n",scount);    printf("the digit of other element is:%d\n",ocount);}
[解决办法]
for(;(c = getchar()) <= EOF;)
这句是有问题的。应该改成：
for(;(c = getchar()) != EOF;) (或者while ((c = getchar() != EOF))输入EOF需要通过按键输入，在linux下是按：ctrl+d,在windows下是按：ctrl+z吧。

[解决办法]
while((c = getchar())!= EOF) //for(;(c = getchar()) <= EOF;)
{

if ((c>='A'&& c<='Z')||(c>='a' && c<='z'))
ccount++;
else if((c>='0' && c<='9'))
ncount++;
else if(c == ' ')
scount++;
else
ocount++;
}
[解决办法]
EOF的值通常是 －1。  ascii码常用的是0－127。 你这么整，他必须全是 0 啊 ！！

[code=C/C++][/code]
#include<stdio.h>
main()
{
char c;
int ncount,ccount,scount,ocount;
 ncount = ccount = scount = ocount = 0;

for(;(c = getchar()) !='0' ;)//EOF=》'0'
{

if ((c>='A'&& c<='Z')||(c>='a' && c<='z'))
ccount++;
else if((c>='0' && c<='9'))//要用字符
ncount++;
else if(c == ' ')
scount++;
else
ocount++;
}

printf("the digit of character is:%d\n",ccount);
printf("the digit of number is:%d\n",ncount);
printf("the digit of space is:%d\n",scount);
printf("the digit of other element is:%d\n",ocount);
}
