Calculator in C programming with Source Code

Calculator in C programming; We will look at how to write a calculator program in the C programming language in this chapter.

A calculator is a compact electronic device that performs arithmetic operations such as addition, subtraction, multiplication, division, and percentage calculations.

We have included a downloadable zip file in C at the end of the program so that you may run the following codes.

Example Program

#include <stdio.h>

int main() {

  char op;
  double first, second;
  printf("Enter an operator (+, -, *, /): ");
  scanf("%c", &op);
  printf("Enter two operands: ");
  scanf("%lf %lf", &first, &second);

  switch (op) {
    case '+':
      printf("%.1lf + %.1lf = %.1lf", first, second, first + second);
      break;
    case '-':
      printf("%.1lf - %.1lf = %.1lf", first, second, first - second);
      break;
    case '*':
      printf("%.1lf * %.1lf = %.1lf", first, second, first * second);
      break;
    case '/':
      printf("%.1lf / %.1lf = %.1lf", first, second, first / second);
      break;
    // operator doesn't match any case constant
    default:
      printf("Error! operator is not correct");
  }
}

Output

Enter an operator (+, -, *, /): *
Enter two operands: 2
2
2.0 * 2.0 = 4.0 

What is the importance of Calculator in c code?

The objective of a calculator is to perform accurate calculations quickly.

A calculator should, to the extent possible, free the user of the need to perform mental calculations and rely on paper.

By learning C, you will be able to comprehend and see the inner workings of computer systems (such as memory management and allocation), as well as their design and the broader concepts that drive programming.

As a computer language, C enables you to create more complex and comprehensive applications.

What is the use of Calculator in c language?

It’s also a computer program that acts like a handheld calculator. Calculator apps allow you to perform basic math calculations without having to leave your computer.

A calculator desk attachment is included with the Apple Macintosh. A calculator is also included with Microsoft Windows.

About the Project

We will look at how to write a calculator program in the C programming language in this chapter. A calculator is a compact electronic device that performs arithmetic operations such as addition, subtraction, multiplication, division, and percentage calculations.

It simplifies and expedites our calculations. In some cases, we employ a scientific or sophisticated calculator to solve difficult calculations such as trigonometry functions, exponential operators, degrees, radians, log functions, hyperbolic functions, and so on.

The C program to Print Pyramid Pattern below contains all of the necessary and vital aspects that first-year, second-year, and final-year IT students can utilize for college assignments. The project was written entirely in C and edited with the Codeblocks editor.

Project Details and Technology

To start executing this project, make sure that you have  Codeblocks or any platform of code editor installed on your computer.
