Program on calculator in c

To make a simple calculator in C programming that performs basic four mathematical operations, use the switch case to identify the input operator to perform the required calculation as shown in the program given below. Here is a simple menu-driven program based on simple calculation like addition, subtraction, multiplication and division according to user's choice:.

Here is the initial snapshot of the sample run:. For example, if user enters 2 as choice and 20 as first number, then 10 as second number. Press 5 to exit the calculation process. It makes our calculations easier and faster. It is a portable device that can use anywhere to perform simple mathematical operations. We use a scientific or sophisticated calculator in some situations, where we need to solve complex calculations like trigonometry functions, exponential operators, degrees, radians, log functions, hyperbolic functions etc.

Let's discuss the various ways to create a calculator program in the C language. Step 1: Declare local variables n1, n2, res, opt. For example, where n1 and n2 take two numeric values, res will store results and opt variable define the operator symbols.
