Building your own calculator program not only enhances your understanding of fundamental programming concepts but also provides you with a practical application to solve mathematical problems.<\/p>\n<p>In this article, we will explore the process of creating a calculator program in the C programming language. We will take you through the step-by-step development of a calculator that can perform basic arithmetic operations, including addition, subtraction, multiplication, and division. Additionally, we will expand the functionality by incorporating more advanced operations, such as exponentiation and square root calculations.<\/p>\n<p>Throughout the article, we will provide clear explanations and code examples, making it accessible for both beginners and experienced programmers. By following along, you will gain a deeper understanding of core programming concepts, such as user input, control flow, and function implementation.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/prepbytes-misc-images.s3.ap-south-1.amazonaws.com\/assets\/1684992544235-1-01%20-%202023-05-25T105848.752.png\" alt=\"\" \/><\/p>\n<h2>Algorithm for a Calculator Program in C<\/h2>\n<ul>\n<li><strong>Step 1:<\/strong> Declare the following variables: 1, 2, answer, and operation.

Subtraction, multiplication, and division will be carried out in accordance with whether the provided operator is -.* or \/. Since we cannot divide any integer by zero, we shall verify additional conditions in a division that number 2 is not zero. We will prompt the user to enter a valid operator if the requested operator is not one of the available operators. We can see from the result that we started by taking the operator input, which is multiplication.

The user is then asked to provide input for numbers 1, 2, and op. Now, we will use the switch statement to check for the input operation; if the supplied operator is +, we will add the given values and output the result. Subtraction, multiplication, and division will be carried out in accordance with whether the provided operator is -.* or \/. Since we cannot divide any integer by zero, we shall verify additional conditions in a division that number 2 is not zero.We will utilize the default statement to prompt the user to provide a valid operator if the given operator is not one of the available operators. We can see from the output that we first enter the subtraction operator, then we take the two values 23 and 11, and last we subtract the two numbers, printing the result as 12.<\/p>\n<h2>Approach 3: The Simple Calculator Program in C using the Functions and Switch Case.<\/h2>\n<p>In this program, four separate functions (add, subtract, multiply, and divide) are defined to perform the corresponding arithmetic operations. The main function prompts the user to enter an operator (+, -, *, or \/) and two numbers. The switch case statement is then used to determine the chosen operator and call the appropriate function.<\/p>\n<p>The result of the calculation is stored in the result variable and displayed on the screen. The program handles invalid operators gracefully and terminates execution if an error occurs during division by zero.<\/p>\n<h3>Simple Calculator Program in C Using Functions<\/h3>\n\t\t\t\t\t\t<style>\r\n\t\t\t\t\r\n\t\t\t\t\t#tab_container_11289 {\r\n\toverflow:hidden;\r\n\tdisplay:block;\r\n\twidth:100%;\r\n\tborder:0px solid #ddd;\r\n\tmargin-bottom:30px;\r\n\t}\r\n\r\n#tab_container_11289 .tab-content{\r\n\tpadding:20px;\r\n\tborder: 1px solid #e6e6e6 !important;\r\n\tmargin-top: 0px;\r\n\tbackground-color:#ffffff !important;\r\n\tcolor: #000000 !important;\r\n\tfont-size:16px !important;\r\n\tfont-family: Open Sans !important;\r\n\t\r\n\t\tborder: 1px solid #e6e6e6 !important;\r\n\t}\r\n#tab_container_11289 .wpsm_nav-tabs {\r\n    border-bottom: 0px solid #ddd;\r\n}\r\n#tab_container_11289 .wpsm_nav-tabs > li.active > a, #tab_container_11289 .wpsm_nav-tabs > li.active > a:hover, #tab_container_11289 .wpsm_nav-tabs > li.active > a:focus {\r\n\tcolor: #000000 !important;\r\n\tcursor: default;\r\n\tbackground-color: #ffffff !important;\r\n\tborder: 1px solid #e6e6e6 !important;\r\n}\r\n\r\n#tab_container_11289 .wpsm_nav-tabs > li > a {\r\n    margin-right: 0px !important;

We then used the user&#8217;s input to complete the action as needed. Now, we will use the switch statement to check for the input operation; if the supplied operator is +, we will add the given values and output the result. Subtraction, multiplication, and division will be carried out in accordance with whether the provided operator is -.* or \/. Since we cannot divide any integer by zero, we shall verify additional conditions in a division that number 2 is not zero. We will utilize the default statement to prompt the user to provide a valid operator if the given operator is not one of the available operators. We can see from the output that we first enter the multiplication operator, then we take the two values 3 and 4, and last we multiply the two numbers, printing the result as 12.<\/p>\n<p><strong>Conclusion<\/strong><br \/>\nBy customizing and expanding the calculator program, readers have the opportunity to explore further and adapt it to their specific needs and preferences. Whether you are a beginner learning the basics of C programming or an experienced developer honing your skills, the process of building a calculator program provides valuable insights and practical experience.<\/p>\n<p>As you continue your programming journey, the knowledge and techniques gained from building a calculator program can be applied to a wide range of programming projects, from mathematical simulations to financial applications.<\/p>\n<p>In conclusion, the calculator program in C serves as an excellent exercise to sharpen your coding abilities and solidify your understanding of programming fundamentals.
