A Fibonacci sequence is a sequence of numbers (called Fibonacci numbers) in which each number is the sum of the two preceding ones as following: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... The task is to implement two functions in C Plot the Fibonacci numbers from n = 1 to 14, together with F(n) = n^2 use clion by c codes

Sure, here is the C code to generate Fibonacci sequence and calculate n^2 for n = 1 to 14.

#include <stdio.h>

// Function to calculate Fibonacci number
int fibonacci(int n) {
    if (n <= 1)
        return n;
    else
        return(fibonacci(n-1) + fibonacci(n-2));
}

// Function to calculate square of a number
int square(int n) {
    return n * n;
}

int main() {
    int i;

    printf("n\tFibonacci\tSquare\n");
    for (i = 1; i <= 14; i++) {
        printf("%d\t%d\t\t%d\n", i, fibonacci(i), square(i));
    }

    return 0;
}

This code first includes the standard input/output library. Then it defines two functions: fibonacci and square. The fibonacci function calculates the nth Fibonacci number using a recursive approach. The square function calculates the square of a number.

In the main function, it loops from 1 to 14, and for each number, it calculates and prints the Fibonacci number and the square of the number.

Please note that this code does not plot the numbers. C is not typically used for plotting graphs. For that, you might want to use a library or a different language that supports plotting, such as Python with matplotlib. Also, CLion is just an IDE, it doesn't provide any specific functionality for plotting or for running C code. You can run this C code in any environment that supports C.
