c++ - Making my do while loop neater by removing repeating code -


hi here question.

write program uses do-while statement. reads in integer n keyboard. if n not in range 1 10 makes audible “beep” , asks integer. if n in correct range, writes out “you have input n” , exits.

here answer.

#include <iostream> #include <windows.h> using namespace std;  void main() {     int number = 0;         {       cout << "enter integer." << endl;       cin >> number;       if (!(number >= 1 && number <= 10))       {         beep(400, 400);       }     }     while (!(number >= 1 && number <= 10));     cout << "you have input " << number << endl;     system("pause"); } 

you can see line

(!(number >= 1 && number <= 10)) 

is repeated. there workaround this?

#include <iostream> #include <windows.h> using namespace std;  void main() {     int number = 0;     bool invalid_input = true;         {       cout << "enter integer." << endl;       cin >> number;       invalid_input = !(number >= 1 && number <= 10);        if (invalid_input)       {         beep(400, 400);       }     }     while (invalid_input);     cout << "you have input " << number << endl;     system("pause"); }
