How to develop a C++ program to read a non-linear equation and to read a linear system of equations..???

[JosAH]

A non-linear equation? What sort of equation? A polynomial equation or what?
About that linear system; do you want to read in all coefficients in text form or
binary or what? Your question is too broad and too vague to answer.

kind regards,
