在目標C中顯示百分比

-5

我試圖在考試結束時向用戶顯示百分比。基本上，我需要一行代碼，將myScore除以70的問題總數。任何幫助都將非常感謝。在目標C中顯示百分比

這是我的考試結束碼：

NSInteger endOfQuiz = [theQuiz count]; 
if((((questionNumber - 1) * 6) + 6) == endOfQuiz) 
{ 
    // Game is over. 
    if(myScore >= 49) 
    { 
     NSString *finishingStatement = [[NSString alloc] initWithFormat:@"Practice Exam concluded. Congratulations, you have passed with a 70%% or better! \nYou scored %i out of 70!", myScore]; 
     theQuestion.text = finishingStatement; 
     answerResult.text = @""; 
     counterLabel.text = @"";  } 
    else 
    { 
     NSString *finishingStatement = [[NSString alloc] initWithFormat:@"Practice Exam concluded. Unfortunately, you have failed with less than 70%%, keep practicing! \nYou scored %i out of 70.", myScore]; 
     theQuestion.text = finishingStatement; 
     counterLabel.text = @""; 

    } 
    theLives.text = @""; 
    answerResult.text = @""; 
    // Make button 1 appear as a reset game button 
    restartGame = YES; 
    [answerOne setHidden:NO]; 
    [answerOne setTitle:@" Try this Practice Exam again" forState:UIControlStateNormal]; 

}

那麼，什麼是錯'浮動比例= 100×（浮動）將myScore/70;「（你乘以100得到的百分比。） – Caleb

除法運算符在C（以及因此的Objective-C）爲/。

myScore * 100/70

看起來'myScore'可能是一個整數，所以你的表現？也會產生一個int，嘗試將'myScore'轉換爲'float'或者簡單地將'70'改爲'70.0' – Caleb

即使它不是浮點數，它也會工作，因爲我們先乘以100，除以70會產生百分比的整數部分 – Brigham

謝謝！我知道有一個簡單的答案，而迦勒，你是對的，讚賞它們。 – user2175392
