EASY WAYS TO SUBTRACT FIVE NUMBERS IN DART

Introduction

Dart is a modern, open-source programming language developed by Google, known for its use in developing mobile and web applications with the Flutter framework. Learning Dart involves understanding basic operations like arithmetic calculations. In this example, we will write a simple Dart program to subtract five numbers.

Dart Program to Subtract Five Numbers

Here’s a basic Dart program to subtract five numbers:

void main() {
  // Define the five numbers
  int num1 = 100;
  int num2 = 20;
  int num3 = 15;
  int num4 = 10;
  int num5 = 5;

  // Perform the subtraction
  int result = num1 - num2 - num3 - num4 - num5;

  // Print the result
  print('The result of subtracting the five numbers is: $result');
}

Explanation of the Code

• void main(): This is the entry point of the Dart program. The main function is where the execution of the program begins.
• int num1 = 100;: Here, we define an integer variable num1 and initialize it with the value 100.
• int num2 = 20;: Similarly, we define another integer variable num2 and initialize it with the value 20.
• int num3 = 15;: This line defines the third integer variable num3 with the value 15.
• int num4 = 10;: This line defines the fourth integer variable num4 with the value 10.
• int num5 = 5;: This line defines the fifth integer variable num5 with the value 5.
• int result = num1 - num2 - num3 - num4 - num5;: We perform the subtraction of all five numbers and store the result in the variable result.
• print('The result of subtracting the five numbers is: $result');: Finally, we use the print function to display the result of the subtraction on the console. The $result is used to insert the value of result into the string.

Output

When you run the program, the output will be:

The result of subtracting the five numbers is: 50

Conclusion

This simple Dart program demonstrates basic arithmetic operations, specifically subtraction. By defining integer variables and performing subtraction, we can easily handle mathematical tasks in Dart. This foundational knowledge is essential as you progress to more complex programming concepts and applications. Dart’s straightforward syntax and powerful features make it a great choice for various programming tasks.
