Write Fortran program that integrates a Gaussian function from x_0 to x_N over N equidistant intervals using the trapezoid rule.
Inputs: integrating range from x_0 to x_N (real64), number of intervals N (integer); parameters of the Gaussian function a, b, c (real64).
Output: value of the integral (real64)
Implement the Gaussian function and the integrating loop as internal subprograms (pure function and a subroutine respectively) with proper intents in/out etc
