数组的应用示例

• 任意输入【0,9】范围内的整数，统计输入的每一种数字的个数并输出，输入-1结束程序

#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("请输入0～9之间的任意整数：\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)		//加入一个if判断，只输出用户输入了的数字个数{printf("%d:%d\n",i,count[i]);}}return 0;
