Just put your a,b,c values into this formula

At the very least, you should be able to print a prompt, and read some values.

Thanks for the reply. I believe there is some confusion, I am not looking for quadratic equation solving. I want to solve Non Linear Programming for optimization. Just for your reference, I want to perform the same thing what a solver does on excel. I found some stuff on linear programming; however, not able to find anything for non linear programming.

Cheers.

Having never used the excel solver, I'll answer anyway. Search the internet for multi-dimensional optimization algorithms. I like Nelder-Mead (also known as amoeba), no need to compute that nasty matrix of partial derivatives, although there are codes that estimate the Jacobian. Links:

gsl 1D minimization

gsl multi-dimensional minimization

netlib search
look for simplex
