Basic formatting in C++ - Mini Project: Build & Apply

Basic formatting

📖 Scenario: You are creating a simple program to display a person's name and age in a nicely formatted way. This is like writing a friendly introduction card.

🎯 Goal: Build a C++ program that stores a person's name and age, then prints a formatted sentence introducing the person.

📋 What You'll Learn

Create variables to store a person's name and age

Use a helper variable to store a greeting message

Combine the variables into a formatted sentence using std::cout

Print the final formatted sentence

💡 Why This Matters

🌍 Real World

Formatting text output is useful for creating user-friendly messages in console programs, reports, and logs.

💼 Career

Basic formatting skills are essential for software developers to display information clearly and professionally.

1

Create variables for name and age

Create a std::string variable called name and set it to "Alice". Create an int variable called age and set it to 30.

C++

#include 
#include 

int main() {
    // Create a std::string variable called name and set it to "Alice"
    // Create an int variable called age and set it to 30
    // Your code here

    return 0;
}

Need a hint?

Use std::string name = "Alice"; and int age = 30; inside main().

2

Add a greeting message variable

Create a std::string variable called greeting and set it to "Hello".

C++

#include 
#include 

int main() {
    std::string name = "Alice";
    int age = 30;
    // Create a std::string variable called greeting and set it to "Hello"
    // Your code here

    return 0;
}

Need a hint?

Use std::string greeting = "Hello"; inside main().

3

Combine variables into a formatted sentence

Use std::cout to print the sentence combining greeting, name, and age in this exact format: Hello, my name is Alice and I am 30 years old.

C++

#include 
#include 

int main() {
    std::string name = "Alice";
    int age = 30;
    std::string greeting = "Hello";
    // Use std::cout to print the formatted sentence
    // Your code here

    return 0;
}

Need a hint?

Use std::cout << greeting << ", my name is " << name << " and I am " << age << " years old." << std::endl;

4

Print the final formatted sentence

Run the program and ensure it prints exactly: Hello, my name is Alice and I am 30 years old.

C++

#include 
#include 

int main() {
    std::string name = "Alice";
    int age = 30;
    std::string greeting = "Hello";
    std::cout << greeting << ", my name is " << name << " and I am " << age << " years old." << std::endl;
    // Your code here

    return 0;
}

Need a hint?

Run the program and check the output matches exactly.
