C++语言中用程序实现读入一个包含标点符号的字符串，将标点符号去除后输出字符串剩余的部分

#include <iostream>
#include <string>
using namespace std;

int main()
{
string s("带标点符号的字符串");
for (string::size_type i = 0; i != s.size(); ++i)<span style="font-family: Arial, Helvetica, sans-serif;">{</span><span style="font-family: Arial, Helvetica, sans-serif;">if (ispunct(s[i]))</span><span style="font-family: Arial, Helvetica, sans-serif;">{</span><span style="font-family: Arial, Helvetica, sans-serif;">for (string::size_type j = i; j != s.size(); ++j)</span><span style="font-family: Arial, Helvetica, sans-serif;">{s[j] = s[j + 1]};</span><span style="font-family: Arial, Helvetica, sans-serif;">--i;</span><span style="font-family: Arial, Helvetica, sans-serif;">}</span><span style="font-family: Arial, Helvetica, sans-serif;">}</span>
