[問題] 求任意整數中出現的特定數字個數
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
額外使用到的函數庫(Library Used): (Ex: OpenGL, ...)
問題(Question)：輸入一個整數 判斷裡面含有多少個數字 7
餵入的資料(Input)：任意整數(不限位數)
預期的正確結果(Expected Output)：算出有幾個 7
錯誤結果(Wrong Output)：數字亂碼
程式碼(Code)：(請善用置底文網頁, 記得排版)
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int counter;
int n;
int digit;
printf("Enter a positive integer: ");
scanf("%d" , &n);
while (n!=0) {
digit = n%10;
if(digit == 7){
counter++;
}
n = n/10;
}
printf("There are %d seven" , counter);
system("pause");
return 0;
}
補充說明(Supplement)：
大家好 我是初學者正在練習程式設計藝術這本書的習題...才第三章我就快滅亡了
請求前輩支援 @@" 我已經想到我的極限了 也盡可能的在找出錯誤 可是就是找不出來
執行後也依舊是亂碼 我適用 dev 來跑的 希望前輩們能救救小弟 已經開始體會跑不
出來那種寢食難安的感覺了 我現在在看別的都會衣值回頭去想 快要精神分裂了...!!
