• 任意輸入【0,9】范圍內的整數，統計輸入的每一種數字的個數并輸出，輸入-1結束程序

#include <stdio.h>
int main(){const int number = 10;int x;int i;int count[number];for ( i = 0; i < number; i++){count[i] = 0;}printf("請輸入0～9之間的任意整數：\n");scanf("%d",&x);while (x != -1){if (x >=0 && x <= 9){count[x]++;}scanf("%d",&x);}for ( i = 0; i < number; i++){if (count[i] > 0)		//加入一個if判斷，只輸出用戶輸入了的數字個數{printf("%d:%d\n",i,count[i]);}}return 0;
