![]() ![]() To do this, there is an inbuilt function called pow(base, exponent).Īs an expansion to it, if you want to challenge yourself, try to write the program for pow(base, exponent). So, we take these two things from the user and calculate the exponential of the base. The power - Number decides how much the base should raised and how many times to do it? The base - Number should be raised or multiplied by itself for power number times. Two things in an exponential are needed for the calculation of the result. The exponential function is more of a smaller and easier-to-write function. We finished two of the primary operations. If you want to incorporate more then, it is better to use a switch case. We didn’t use a switch case here because we only need 2 cases. For the calculation of output, we directly use the sin() and cos() functions from the math.h library. ![]() So, don’t get confused thinking it is a wrong answer.įor this tutorial, we only provide two trigonometric functions sine and cosine. If we enter 30 as an input to the sine function, it considers 30 radians. ![]() In our calculator, we get the result as an input of radians. In general, A calculator provides the result based on the choice of degree or radians. The rest is self-describing in that function. So, we take two variables as input for the arithmetic operations. In this calculator, we only operate on two inputs. We use switch-case because it’s made for cases where we provide multiple options to the user. If-else and else if loops are also an option. Inside the arithmetic() function, we provide addition, subtraction, multiplication, and division operations. It goes on until the user enters n which stands for “no” in this case. In the main function, we start a while loop for taking the input from the switch case. ![]() Basics of C++ functions - To make the program seem clean and reusable for further expansions.ġ26: } Code Explanation The main() function.While loops - For infinite loop of switch case.Place b in a and c in b then place a+b in c to print the value of c to make and print Fibonacci series as shown here in the following C++ program. C++ Sample Coding Print Fibonacci Series Use the three variable say a, b and c. Logic to find determinant of a matrix in C. Switch Case - To switch between the options Find determinant of a 2x2 matrix and 3x3 matrix.Before we go into the explanation, let’s see the concepts of C++ you should know to understand the code and replicate it. ![]()
