Write a program that contains a main function, a double custom_operator_function(int op_type, double x, double y), a double min(double,double), a double max(double x,double y), and a double pow(double x, int y). The main function is used to call the custom operator function. Next, the custom operator function calls the min/max/pow functions based on the op_type. From the main, call the custom operator function with the three inputs 1/-3/5, 2/4/5, and 3/4/5. Print the result of each input to screen. i) The custom operator function calls the min, max, or pow function based on the value of the parameter op_type (1=min), (2=max), (3=pow) and returns the result of the called function. The arguments passed to the min/max/pow function are the parameters x and y. ii) Do not use the min, max, and pow functions from the math library.

Please use C programming.
