First, let's write a function that calculates Fibonacci numbers up to a specified count. We will use a simple iterative approach for this purpose.

#include <stdio.h>

void fibonacci(int count) {
    int first = 0, second = 1, next, i;
    printf("Fibonacci Series: %d, %d", first, second);
    for (i = 2; i < count; i++) {
        next = first + second;
        first = second;
        second = next;
        printf(", %d", next);
    }
}

int main() {
    int count;
    printf("Enter the number of Fibonacci numbers to generate: ");
    scanf("%d", &count);
    fibonacci(count);
    return 0;
}
            

This code allows users to input how many Fibonacci numbers they want to see, and the program will generate them accordingly.

Compile the code using GCC or your preferred C compiler:

gcc -o fibonacci fibonacci.c

Execute your program to see the Fibonacci sequence:

./fibonacci

This will prompt you to enter the number of terms you wish to generate and display the sequence.
