A C language version of a polynomial:

A mixed numeric and symbolic expression:

C formatting for an arbitrary function:

A composite power:

A vector:

A matrix:

Compute the analytic Hessian for a multivariate function for use in C code:

When an input evaluates to CForm[expr], CForm does not appear in the output:

Out is assigned the value x², not CForm[x^2]:

CForm formats expressions like C code:

FortranForm formats expressions like Fortran code:

Names of functions output by CForm may be different from the names used by the specific C library:

In order to compile the C code generated, a header file found at the following location may need to be included:

Even when an output omits CForm from the top level, it is not stripped from subexpressions:

The output does not have CForm in it:

However, the variable e does have CForm in it, which may affect subsequent evaluations:

The product is not evaluated due to the intervening CForm:

Assign variables first and then apply CForm to the result to maintain computability:
