C#.net代码错误请参阅以下代码并纠正错误 [英] C# .net code error please see the following code and rectify the Error
问题描述
Hello Friends,
我在c#语言的帮助下练习编程工作。
我发现这个程序无法打印所需的输出我想要的。
请帮我找出错误。
谢谢你。
代码。
...................... ......
使用系统;
使用 System.Collections.Generic;
使用 System.Linq;
使用 System.Text;
命名空间 logical_star_outer_pyramid
{
class 计划
{
静态 void Main( string [] args)
{
Console.WriteLine( 输入你的号码跨度>);
int i = int .Parse(Console.ReadLine());
for ( int j = 0 ; j < = i; j ++)
{
for ( int k = 1 ; k < =(i - j); k ++)
Console.Write( );
for ( int l = 1 ; l < = j; l ++)
{
if ( l == 1 || l == j || i == j)
Console.Write( * + );
else
Console.Write( );
}
Console.WriteLine();
}
Console.ReadLine();
}
}
}
输出应该是这样的: -
输入数字: -
4; IE;外金字塔(内金字塔或星星不应出现)
<前lang =text> *
* *
* *
* * * * *
为什么使用3个循环?
for ( int j = 0 ; j < = i; j ++)
{
for ( int k = 1 ; k < =(i - j); k ++)
Console.Write( 跨度>);
for ( int l = 1 ; l < = j; l ++)
你只需要使用2个循环!想象一下,你需要填充数组...
伪代码:
string stars = string .Empty;
for ( int i = 1 ; i< = NumberEnteredByUser; i ++)
{
for (j = 1 ; j< = i; j ++)
{
// concat *
stars = string .Concat(stars, *跨度>);
}
Console.WriteLine(星星) ;
// clear string
stars = 字符串跨度> .Empty;
}
知道了吗?
注意字符串是不可改变的。这是什么意思?在这里阅读:为什么字符串是不可变的,有什么影响它是什么? [ ^ ]
Hello Friends,
I am practicing my programing assignment with the help of c# language.
I found that this program unable to print the desired output what i want.
Please help me out in finding the error.
Thank you.
Code.
............................
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace logical_star_outer_pyramid
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Enter your Number");
int i = int.Parse(Console.ReadLine());
for (int j = 0; j <= i; j++)
{
for (int k = 1; k <= (i - j); k++)
Console.Write(" ");
for (int l = 1; l <= j; l++)
{
if (l == 1 || l == j || i == j)
Console.Write("*" + "");
else
Console.Write(" ");
}
Console.WriteLine();
}
Console.ReadLine();
}
}
}
output should be like:-
Enter the Number:-
4;I.E; Outer Pyramid (inner pyramid or stars should not present)
*
* *
* *
* * * * *
Why do you use 3 loops?
for (int j = 0; j <= i; j++) { for (int k = 1; k <= (i - j); k++) Console.Write(" "); for (int l = 1; l <= j; l++)
You need to use only 2 loops! Imagine, you need to fill array...
In pseudo-code:
string stars = string.Empty; for (int i = 1; i<=NumberEnteredByUser; i++) { for (j = 1; j<=i; j++) { //concat * stars = string.Concat(stars, "*"); } //print Console.WriteLine(stars); //clear string stars = string.Empty; }
Got it?
Note that string is immutable. What it means? Read here: Why strings are immutable and what are the implications of it?[^]
