循环和If语句和功能

Question

我不知道如何在我点击“＆nbsp;或者＆＃39; N＆＃39; ...一旦我把它最终关闭了所以我怎么回到循环中？

int counter = 5;
while(counter > 1)
linear(xcoordinateone, xcoordinatetwo, ycoordinateone, ycoordinatetwo, slope, intercept); //calling
{
cout<<"The points you entered define the function: y = " << slope << xone << "+" << intercept;
cout << "\n Do you want to continue?";
if (answer == 'N' || answer == 'n');    
    cin >> answer;
    return 0;
}

Answer 1

你可以在while循环中使用多个条件：

answer = 'y';
while(answer != 'N' && answer != 'n'){
    cout << "\n Do you want to continue?";
    cin >> answer;
}

Answer 2

do {
    // do stuff
    cout << "\n Do you want to continue?";
    cin >> answer;
} while (answer!='N' && answer!='n');
