EASY WAYS TO PRINT SUM OF FIVE NUMBERS IN TYPESCRIPT

Introduction

In this task, we will write a simple TypeScript program to calculate and print the sum of five numbers. TypeScript is a strongly typed superset of JavaScript that adds static typing and other features to help with larger applications. This program will introduce basic TypeScript concepts such as variables, functions, and input/output operations.

// Function to add five numbers
function addFiveNumbers(num1: number, num2: number, num3: number, num4: number, num5: number): number {
    // Sum the five numbers and return the result
    return num1 + num2 + num3 + num4 + num5;
}

// Declare five numbers
let number1: number = 10;
let number2: number = 20;
let number3: number = 30;
let number4: number = 40;
let number5: number = 50;

// Call the function to add the numbers
let sum: number = addFiveNumbers(number1, number2, number3, number4, number5);

// Print the result
console.log("The sum of the five numbers is: " + sum);

Explanation of Each Line:

1. Function Declaration (function addFiveNumbers...):
   • This line defines a function called addFiveNumbers that takes five parameters (num1, num2, num3, num4, num5). Each parameter is of type number. The function will return a number, which is the sum of the five numbers.
2. Summing the Numbers (return num1 + num2 + num3 + num4 + num5;):
   • The body of the function contains a simple statement that adds the five numbers together and returns the result. This line does the actual addition.
3. Declaring Variables (let number1: number = 10;):
   • Here, we declare five variables (number1 through number5) using the let keyword. Each variable is of type number, and we initialize them with values: 10, 20, 30, 40, and 50 respectively.
4. Calling the Function (let sum: number = addFiveNumbers...):
   • This line calls the addFiveNumbers function, passing the five declared numbers as arguments. The result (sum of the numbers) is stored in a variable called sum.
5. Printing the Result (console.log(...)):
   • This line prints the result to the console. The console.log() method is used for output. The message includes the text "The sum of the five numbers is: " concatenated with the value of sum.

Explanation of Output:

When the program is run, it will output the following line to the console:

The sum of the five numbers is: 150

Explanation:

The function addFiveNumbers calculates the sum of 10 + 20 + 30 + 40 + 50, which equals 150.

The console.log() function outputs the text "The sum of the five numbers is: " followed by the calculated sum (150).

Conclusion

This TypeScript program demonstrates how to declare variables, write a simple function, and print the result in the console. The program can be easily modified to take user input or change the numbers for a more dynamic calculation. The core idea is that functions in TypeScript allow us to encapsulate logic and reuse it as needed.
