public static void main(String[] args) {
int maxNum, sum, counter; // input value
Scanner input = new Scanner(System.in);
System.out.print("How many odd numbers should I add up?: ");
maxNum = input.nextInt();
sum = 0;
for (counter = 1; counter < maxNum; counter++)
{
sum = counter + maxNum;
}
System.out.println("\n" + "The sum of the odd numbers between 1 and " + maxNum + " is: " + sum);
}
并且根据该特定代码，它应该仅通过奇数来解决加法问题。
现在，根据输出，我尝试了一个数字5。
How many odd numbers should I add up?: 5
The sum of the odd numbers between 1 and 5 is: 9
有用。但是当我尝试另一个数字10时，出现了问题：
How many odd numbers should I add up?: 10
The sum of the odd numbers between 1 and 10 is: 19
我知道我的数学问题，但是从1到10的奇数加起来不会等于19，而是加起来等于25。
代码出了点问题。谁能找出问题所在？
for (counter = 1; counter < maxNum; counter+=2)
{
sum += counter;
}
您输入的号码有误。
