Help please

I want to get some number as input and output them in order from bigger to smaller int i,j,t; double a=new double[5]; for(i=0;i<a.Length;++i){ a[i]=double.Parse(Console.ReadLine()); } /*bubble alghoritm */ for(j=0;j<a.Length;++j){ for(i=0;i<a.Length-1;++i){ if(a[i]<a[i+1]){ t=a[i]; a[i]=a[i+1]; a[i+1]=t; } } }

You are using a[i] , and i not changing, it's value is already exceeded array length. instead you need a[mid]. And use < instead of > in if condition. while(low<=high){ if(a[mid]==10){ //(1) find=true; break; } if(a[mid]<10){ //(2) high=mid-1; } else{ low=mid+1; } j++; mid=(low+high)/2; }

You need to learn sorting algorithms. You are trying bubble sort algorithm, that required swapping of values when not in order. (Start loop from 1) https://www.sololearn.com/learn/774/?ref=app https://www.sololearn.com/learn/649/?ref=app (Is this links are working fine..?)

* Accept single input number. * From input number to 0, run loop by reducing 1 in each iteration * print number. edit: question changed?

--snip-- int i,n; int[] a=new int[5]; for(i=0;i<5;i++){ a[i]=Convert.ToInt32(Console.ReadLine()); } Array.Sort(a); Array.Reverse(a); foreach (var u in a) Console.Write(u); This is simple way, but has a lots ways for that..

--snip-- /* for(i=0;i<5;i++){ if(a[i]>a[i-1]){ Console.WriteLine(a[i]); } else{ Console.WriteLine(a[i-1]); } }*/ for(int u=4;u>=0;--u) Console.WriteLine(a[u]);

Jayakrishna 🇮🇳 Smith Welder i tried those links. I could get the ordering part by buble algorithm. Then i used binary search to check if 10 is in the array that i get it from the user... but it's not working. Why?

Do u want to change elements inside the massive? Or just output?

Anyway, u may use this code. int[] a = new int[5]; for (int i = 0; i < a.Length; ++i) { a[i] = Convert.ToInt32(Console.ReadLine()); } Array.Sort(a); Array.Reverse(a); for (int i = 0; i < a.Length; ++i) { Console.WriteLine(a[i]); } Console.ReadKey();

U are using 2 "for" cycle, but for what? This method is using for 2-dimensional massives. Don't forget about WHILE cycle

I don't know, what are you talking about. I just now checked my code, everything is ok. Maybe problem is in compilation, try to use Microsoft Visual Studio, or onlinegbp

Don't write all in Main method. Make some methods and call its in main method. Get used to do so.. This is example for you with extensions methods, ref operators, etc.. https://code.sololearn.com/cI17b50S15Nx/?ref=app
