C# Program to Convert Decimal to Hexadecimal

This is a C# Program to perform decimal to hexaDecimal conversion.

This C# Program Performs Decimal to HexaDecimal Conversion.

Here the decimal number is first obtained from the user and Is converted to hexadecimal.

Here is source code of the C# Program to Perform Decimal to HexaDecimal Conversion. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

            temp1 = Convert.ToChar(temp);
            hexadecimalNumber[i++] = temp1;
            quotient = quotient / 16;
        }
        Console.Write("Equivalent HexaDecimal Number is ");
        for (j = i - 1; j > 0; j--)
            Console.Write(hexadecimalNumber[j]);
        Console.Read();

}

In this C# program, we are reading the decimal number using ‘decimalnumber’ variable. Decimal is a term that describes the base-10 number system. Hexadecimal is base 16 arithmetic where each digit is a value from 0 to 15, rather than the 0-9 of base 10.

Assign the value of ‘decimalnumber’ variable to ‘quotient’ variable. While loop is used to check the value of ‘quotient’ variable is not equal to 0. If the condition is true, then execute the statement. The ‘temp’ variable is used to compute the modulus of the value of ‘quotient’ variable by 16.

If condition statement, is used to convert integer into character. Check the value of ‘temp’ variable is equal to 0 and decrement the value of ‘j’ variable. If the condition is true, then execute the statement and print the character value of hexadecimalnum[] array character variable.

 
Enter a Decimal Number :

Equivalent HexaDecimal Number is 2D
