查单词

输入一行字符，统计其中有多少个单词。每两个单词用空格（可有多个）隔开，或者标点符号【字符数组】

#include<iostream>using namespace std;int main(){char str[81];gets(str);int i,num=0;for(i=0;str[i]!='\0';++i){if(str[i]==' '&&str[i+1]!=' '||str[i]==','||str[i]=='?'||str[i]=='.'||str[i]==';')num++;}cout<<"There are "<<num+1<<" words in the line."<<endl;return 0;}
