#include <iostream> #include <string> using namespace std; string str; void reverse(int begin,int end) { while(begin<end) { str[begin] = str[begin]^str[end]; str[end] = str[begin]^str[end]; str[begin] = str[begin]^str[end]; begin++; end--; } } int main() { int i,j; while(getline(cin,str)) { int len = str.length(); int begin,end; i = 0; while(i<len) { begin = i; while(i<len&&str[i]!=' ') i++; end = i-1; reverse(begin,end); i++; } reverse(0,len-1); cout << str << endl; } cout << "Hello world!" << endl; return 0; }
例如:I am zhang san. 输出:san. zhang am I;
