Fibonacci Series in C

The C program to generate the Fibonacci series up to a specified number of terms:

#include <stdio.h>

int main() {
    int n, term1 = 0, term2 = 1, nextTerm;

    printf("Enter the number of terms: ");
    scanf("%d", &n);

    printf("Fibonacci Series: ");

    for (int i = 1; i <= n; i++) {
        // Print the current term
        printf("%d, ", term1);

        // Calculate the next term
        nextTerm = term1 + term2;

        // Update terms for the next iteration
        term1 = term2;
        term2 = nextTerm;
    }

    printf("\n");

    return 0;
}

In this program:

• We first prompt the user to enter the number of terms (n) they want in the Fibonacci series.
• We initialize term1 and term2 to 0 and 1, respectively, as these are the first two terms of the Fibonacci sequence.
• Inside the loop, we print term1, which is the current term of the series.
• We calculate the next term (nextTerm) by adding term1 and term2.
• We then update term1 and term2 for the next iteration by assigning term2 to term1 and nextTerm to term2.
• The loop continues until we have printed the specified number of terms.

When you run this program and enter the number of terms you want, it will generate and display the Fibonacci series up to the specified number of terms.
