想請問一下如果就算加上system("PAUSE") 他還是不等我閃一下就過去(依稀看到裡頭有正確結果) 那是什麼問題呢我只是試試看compile程式書上附的光碟裡頭的程式還是他有版權不讓我compile呢? <code from "how to program 5th"> #include <iostream> #include <stdlib.h> #include <string> using std::string; using std::cout; using std::endl; int main() { string s1( "happy" ); string s2( " birthday" ); string s3; // test overloaded equality and relational operators cout << "s1 is \"" << s1 << "\"; s2 is \"" << s2 << "\"; s3 is \"" << s3 << '\"' << "\n\nThe results of comparing s2 and s1:" << "\ns2 == s1 yields " << ( s2 == s1 ?
