Easy Fibonacci Series for CBSE students C++ Programming

 Here's your program!


#include <iostream>

using namespace std;

int main() {

    int n, a = 0, b = 1, c;

    cout << "Enter the number of terms: ";

    cin >> n;

    cout << "Fibonacci Series: ";

    for (int i = 1; i <= n; i++) {

        cout << a << " ";

        c = a + b;

        a = b;

        b = c;

    }

    return 0;

}

So what happened here?

the C++ code for generating the Fibonacci series in more detail.

First, the code prompts the user to enter the number of terms they want in the Fibonacci sequence:

c
cout << "Enter the number of terms: ";
cin >> n;

This code uses cout to display a message asking the user to enter a value, and cin to read in the user's input and store it in the variable n.

Next, the code initializes three variables a, b, and c:

css
int a = 0, b = 1, c;

Here, a and b are set to 0 and 1, respectively, since these are the first two terms in the Fibonacci sequence. c is left uninitialized for now.

The code then enters a loop that runs n times:

css
for (int i = 1; i <= n; i++) {
    // loop body goes here
}

The loop counter variable i is initialized to 1, and the loop runs as long as i is less than or equal to n. In each iteration of the loop, the code prints the current value of a to the console:

c
cout << a << " ";

This code uses cout to display the current value of a, which is the current term in the Fibonacci sequence.

The code then calculates the next term in the sequence by adding a and b, and storing the result in c:

css
c = a + b;

Next, the code updates the values of a and b for the next iteration of the loop:

css
a = b;
b = c;

Here, b is assigned to a, and c is assigned to b. This sets up the values for the next iteration of the loop, since a and b now represent the last two terms in the sequence.

Finally, once the loop has finished running, the code exits and the Fibonacci sequence is displayed in the console.

I hope this helps clarify the C++ code for generating the Fibonacci series!
