关于字符串的问题，如何解决？(语言-c++)

Question

题目描述
输入一行单词序列，相邻单词之间由1个或多个空格间隔，请对应地计算各个单词的长度。

注意，如果有标点符号（如连字符，逗号），标点符号算作与之相连的词的一部分。没有被空格间开的符号串，都算作单词。

输入格式
一行单词序列，最少1个单词，最多300个单词，单词之间用至少1个空格间隔。单词序列总长度不超过1000。

输出格式
依次输出对应单词的长度，之间以逗号间隔。

样例
输入样例
She was born in 1990-01-02 and from Beijing city.
输出样例
3,3,4,2,10,3,4,7,5

问题代码：

#include<cstdio>
#include<cstring>
#include<iostream> 
using namespace std;
char a[1001];
int n,s; 
int main(){
    gets(a);//输入 
    n=strlen(a);//长度 
    for(int i=0;i<n;i++)
    {
        if(a[i]==' ')
        {
        if(s>0)
        printf("%d,",s);
        s=0;
        }
        else
        s++;
    }
    printf("%d",s);
    return 0;

你提交测试选的是C++的话，gets还是换一下吧
可以考虑换成C++里的getline()函数。

如有帮助，还请帮忙点下采纳！感谢！
