[問題] C矩陣問題
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
dev c++
額外使用到的函數庫(Library Used): (Ex: OpenGL, ...)
問題(Question)：
關於課本上面的範例，check a number for repeated digits
程式碼為
#include <stdbool.h>
#include <stdio.h>
int main (void) {
bool digit_seen[10] = {false};
int digit;
long n;
printf("enter number:");
scanf("%1d", &n);
while (n > 0) {
digit = n % 10;
if(digit_seen[digit])
break;
digit_seen[digit] = true;
n /= 10;
}
if (n > 0)
printf("repeated digit\n");
else
printf("no repeated digit\n")
return 0;
}
我完全照著打，可是結果是不管輸入甚麼數字進去，輸出的結果都是no repeated digit..orz
不知道問題出在哪邊，請板友幫幫忙qwq
