Boolean value ....

Question

int z = 10005; bool a = Convert.ToBoolean(z); Console.WriteLine(a); Above code is giving output as :True . Pls explain why? If i want as False what should i do? I get usually confused with boolean data type or if any boolean is used in the program. Pls explain easily for c sharp

Hello You can write like this also : //int d = a * c * 2 / Convert.ToInt32(Math.Pow((c - b) 2)); double d = a * c * 2 / (Math.Pow((c - b) 2)); And output will be same in both case like : figure is hypotenuse Reason : Math.Pow() takes values of double  so d variable can be double So that no need to use int as variable for that Thanks

Hello Everything other than 0 it gives the conversion in Boolean True. You can write condition for True and False. A Boolean value occupies one byte of memory as the following C# example shows. The example must be compiled with the /unsafe switch. The byte's low-order bit is used to represent its value. A value of 1 represents true; a value of 0 represents false. For more info follow the link below https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/bool Thanks

Hello ToBoolean() converts integer to boolean based on equivalent value of provided int value For Example if you write : int z = -10005; int zz = 10005; bool a = Convert.ToBoolean(z); bool aa = Convert.ToBoolean(zz); Console.WriteLine(a); // Prints True Console.WriteLine(aa); // Prints True And if you write : int zzz = 0; bool aaa = Convert.ToBoolean(zzz); Console.WriteLine(aaa); // Prints False For reference : https://msdn.microsoft.com/en-us/library/h0b8dwce(v=vs.110).aspx Thanks

Also in this program: static void Main( string [] args) { int a = 8 b = 6 c = 10; int d = a * c * 2 / Convert.ToInt32(Math.Pow ((c - b) 2)); if (d == (c = Convert.ToInt32(Math.Sqrt (a * a + b * b))) && c == 10) { Console.WriteLine( figure is hypotenuse ); } else { Console.WriteLine( figure is square ); } } 1. why Outputiven convert.toint32 . I guess this is not neded? Pls explain 2. Out put is coming as below. Pls explain why? figure is square
