这是一道水题

#include<iostream>#include<string>#include<stdio.h>#include<math.h>#include<ctype.h>using namespace std;char ch[100005];int main(){	int i,j,n;	scanf("%d",&n);	getchar();	for(i=0;i<n;i++)	{		//对每个测试用例进行初始化变量 		int sum=0;		int cnt=0;				while(scanf("%c",&ch[cnt])!=EOF)		{			//判断输入是否为换行符,若为换行符,则表示当前的测试用例输入结束,完成输出该测试用例的结果 			if(ch[cnt]=='\n')			{				printf("%d\n",sum);				sum=0;				cnt=0;				break;			}			else			{				if(ch[cnt]>='0'&&ch[cnt]<='9')				{					sum++;				}			}		}	}	return 0;}

思路

直接在输入的时候边输入边对输入的字符串进行判断即可。
