Question

基本上我正在编写一种方法，我希望用for循环找到整数的总和。

输出应该是这样的：

Enter value of number 1: 23
Enter value of number 2: 23
Enter value of number 3: 23

The sum is: 69

用户可以选择要添加的多个号码。

我的代码目前看起来像这样：

private void ReadInput()
{
    Console.Write("Number of values to sum?");
    numOfInput = int.Parse(Console.ReadLine());
    Console.WriteLine();

}    

private void ReadInput()
    {
        Console.Write("Number of values to sum?");
        numOfInput = int.Parse(Console.ReadLine());
        Console.WriteLine();
    }

    private void SumNumbers()
    {
        int index;
        int num = 0;
        for (index = 0; index < numOfInput; index++)
        {
            Console.WriteLine("Please give the value of no " + index);
            num = int.Parse(Console.ReadLine());
        }
    }

我该如何解决？

private void SumNumbers()
{
    int index;
    int num = 0;
    for (index = 0; index < numOfInput; index++)
    {
        Console.WriteLine("Please give the value of no  <whole numbers>  " + index);
        num += int.Parse(Console.ReadLine());
        num = sum;


}
}
private void ShowResults()
{
    Console.WriteLine("----------------------------------------------\n");
    Console.WriteLine("The sum is \t{0}", sum);

似乎是解决方案+上面的类仍在使用但是是的。

非常感谢你们

试试这个，

 private static void SumNumbers()
        {
            int numOfInput = 3;
            int index;
            int num = 0;
            for (index = 1; index <= numOfInput; index++)
            {
                Console.WriteLine("Please give the value of no " + index);
                num += int.Parse(Console.ReadLine()); 

            }
            Console.WriteLine("The sum is:" + num.ToString());
            Console.ReadLine(); // to keep console alive 
        }

希望有所帮助，

Answer 2

private void SumNumbers()
{
    int index;
    int num = 0;
    for (index = 0; index < numOfInput; index++)
    {
        Console.WriteLine("Please give the value of no " + index);
        num += int.Parse(Console.ReadLine());
        Console.WriteLine("The sum so far is : "+num.ToString("N0")+". Enter another number to continue summation.");
    }
    Console.WriteLine("Maximum input received. Total is: "+num.ToString("N0")+".");
    Console.ReadLine();
}

Answer 3

这将根据您的需要运作：

int index;
int num = 0;
Console.WriteLine("Number of values to sum: ");
int numOfInput = int.Parse(Console.ReadLine());
for (index = 1; index <= numOfInput; index++)
{
    Console.WriteLine("Please give the value of no " + index);
    num += int.Parse(Console.ReadLine());
}
Console.WriteLine("The sum is: " + num);

将生成以下输出：

要求总和的数量：3

请给出1号的值   23个
  请给出no 2的值   23个
  请给出no 3的值   23个
  总和是：69

使用for循环写入数字的总和
