Can someone please help me to this how on C Language?

Lagrange Interpolation Polynomial will be created for the 5 points (n:0-4) given in the table. P(x) -3 -1 n xn 0-1 10 2 1 32 43 4 NO Print the points (control points) on the console screen. Get the number of points to be used in the Lagrange Interpolation Polynomial from the user. The value of n will be taken from the user (n=number of points-1). A value less than 0 or greater than 4 cannot be entered for the n value. For example; If the user enters O forn, the polynomial will be created using the point with index 0 (the y value is the same for any x value, point). If the user enters 1 for n, the polynomial will be constructed using points with an index of 0- 4. Get the x value to be used in the Lagrange Interpolation Polynomial from the user to create the y (f(x)) value. Print the y value to the screen
