反向打印字符串

STL的应用！

 

代码

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

int main()
{
const string delims(" \t,.;");
string line;
while (getline(cin, line))
{
size_t begIdx, endIdx;
begIdx = line.find_first_not_of(delims);
while (begIdx != string::npos)
{
endIdx = line.find_first_of(delims, begIdx);
if (endIdx == string::npos)
{
endIdx = line.length();
}
for (int i = endIdx-1; i >= static_cast<int>(begIdx); --i)
{
cout << line[i];
}
cout << " ";
begIdx = line.find_first_not_of(delims, endIdx);
}
cout << endl;
}
}
