How to write a C programme for this?

Write a program to perform definite integration of a cubic function f(x)-a+bx+ex+d between two boundary limits p and q. The definite integral of ffx) can be approximated by 6. F(x)=.f(x,Ar where Ar=19-21 and jptilg-2 p and q are the lower and higher boundary limits and Ar is the width of each subinterval. Your program will ask the user for the coefficients a, b, c, d and p, q. Below is a skeleton of the program. #include #de fine N 1000 double funct (double x) double a, b, c, d; int main (void) double funct (double x) return (a*x*xx) (b*x*x) (c) + d
