What are variable data types in computing? Data types are used to specify the type of value that a variable can hold. Different data types have different capabilities and limitations, which help ensure that variables always contain valid information. Common data types include integers, strings, Boo...
In the main function, we prompt users to enter the number of terms they want in the Fibonacci series and store it in the integer variable “n.” We then use a for loop to print the Fibonacci series using the “fibonacci” function. Advantages and Disadvantages of Using Recursive Function ...
