Thread: declaring pointer variable to array of function pointers

I am having following pointer variable declaration

Code:

Static double (*funcs[]) (double) = { sin,cos,tan,asin,acos};

Here funcs is an array of pointers to functions which take double as input and gives double as output with static as storage type am I right.

Ask your compiler! And try these steps:

Write down the function prototype that matches the pointer type you want. Since you are using math functions, that is
double cos(double);

Now add parens around the name and an asterisk.
double (*cos)(double);

Change the name of the function to an alias and make it a typedef.
typedef double (*MathFunction)(double);

Now a declaration of an array of function pointers is:

Code:

MathFunction trigfunctions[] = {sin, cos, tan, asin, acos};
