Develop a C-code that finds the solution of the differential equation below by using Euler's method. The drange of x is 6 to 7

dy/dx=x^(2)-x with y=4 at x=6

Your C-code must contain the following features: (1) use of arrays, (2) use of pointers, (3) use of structure, (4) use of union, (5) use of functions and function calls, (6) formatted output on screen and (7) saving of the same output on a file.
