The following is a fairly good tutorial on the subject:

look at this

double sinf(double x1);//declaration
double cosf(double x1);//declaration
double tanf(double x1);//declaration

int main()
{double y;
int i;
double (*funt[3])(double f)={sinf,cosf,tanf};
double num=30;

	for(i=0;i<3;i++)               {
		y=funt[i](num);
             }
}

double sinf(double z)
{
//put your code here
}
double cosf(double z)
{
//put your code here
}

double tanf(double z)
{
//put your code here
}
