Explanation / Answer

a,

using System;

class Program
{
static void Main()
{
ushort usVar = 52130; /* min. 0 | max. 65535 */
sbyte sbVar = -115; /* min. -128 | max. 127 */
uint uiVar = 4825932u; /* min. 0 | max. 4294967295 */
byte bVar = 92; /* min. 0 | max. 255 */
short sVar = -1000; /* min. -32768 | max. 32767 */

/* Print the numbers on the console */
Console.WriteLine("ushort example: " + usVar);
Console.WriteLine("sbyte example: " + sbVar);
Console.WriteLine("uint example: " + uiVar);
Console.WriteLine("byte example: " + bVar);
Console.WriteLine("short example: " + sVar + Environment.NewLine);
}
}

b,

using System;

class Program
{
static void Main()
{
double number1 = 34.567839023; /* 15-16 digits */
float number2 = 12.345f; /* 7 digits */
double number3 = 8923.1234857;
float number4 = 3456.091f;

/* Print the numbers on the console */
Console.WriteLine("Example of double: " + number1);
Console.WriteLine("Example of float: " + number2);
Console.WriteLine("Example of double: " + number3);
Console.WriteLine("Example of float: " + number4 + Environment.NewLine);
}
}
