Integer types and their ranges in C Sharp (C#) - Mini Project: Build & Apply

Integer types and their ranges

📖 Scenario: You are working on a simple program to understand different integer types in C# and their value ranges. This knowledge helps you choose the right type for storing numbers efficiently.

🎯 Goal: Create variables of different integer types, find their minimum and maximum values, and display these ranges.

📋 What You'll Learn

Create variables of types byte, short, int, and long

Use the built-in properties MinValue and MaxValue to get the ranges

Print the ranges clearly with the type name and its minimum and maximum values

💡 Why This Matters

🌍 Real World

Understanding integer types and their ranges helps you choose the right data type for storing numbers efficiently in real applications, avoiding errors like overflow.

💼 Career

Many programming jobs require knowledge of data types and memory usage to write efficient and safe code, especially in systems programming, game development, and embedded systems.

1

Create variables for integer types

Create variables called myByte, myShort, myInt, and myLong with types byte, short, int, and long respectively. Assign any valid value to each variable.

C Sharp (C#)

// Your code here

Need a hint?

Use the correct type names and assign values within their allowed ranges.

2

Create variables for minimum and maximum values

Create variables called byteMin, byteMax, shortMin, shortMax, intMin, intMax, longMin, and longMax. Assign them the minimum and maximum values of byte, short, int, and long using MinValue and MaxValue properties.

C Sharp (C#)

byte myByte = 100;
short myShort = 30000;
int myInt = 2000000000;
long myLong = 9000000000000000000L;
// Your code here

Need a hint?

Use the type name followed by .MinValue or .MaxValue to get the range limits.

3

Write code to display the ranges

Use Console.WriteLine to print the ranges of each integer type. For example, print "byte range: 0 to 255" using the variables byteMin and byteMax. Do this for byte, short, int, and long.

C Sharp (C#)

byte myByte = 100;
short myShort = 30000;
int myInt = 2000000000;
long myLong = 9000000000000000000L;

byte byteMin = byte.MinValue;
byte byteMax = byte.MaxValue;
short shortMin = short.MinValue;
short shortMax = short.MaxValue;
int intMin = int.MinValue;
int intMax = int.MaxValue;
long longMin = long.MinValue;
long longMax = long.MaxValue;

// Your code here

Need a hint?

Use string interpolation with $"...{variable}..." inside Console.WriteLine.

Run the program and check the output

Run the program and observe the printed output showing the ranges of byte, short, int, and long types.

C Sharp (C#)

byte myByte = 100;
short myShort = 30000;
int myInt = 2000000000;
long myLong = 9000000000000000000L;

byte byteMin = byte.MinValue;
byte byteMax = byte.MaxValue;
short shortMin = short.MinValue;
short shortMax = short.MaxValue;
int intMin = int.MinValue;
int intMax = int.MaxValue;
long longMin = long.MinValue;
long longMax = long.MaxValue;

Console.WriteLine($"byte range: {byteMin} to {byteMax}");
Console.WriteLine($"short range: {shortMin} to {shortMax}");
Console.WriteLine($"int range: {intMin} to {intMax}");
Console.WriteLine($"long range: {longMin} to {longMax}");

// Run and check output

Need a hint?

Check the console output carefully for the exact ranges.
