How can you write a c program that prints a table of trigonometric values for sin cos and tan?

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
const float pi=3.14;
float angle,radian;
clrscr();
printf("Angle\t Radian\t\t sin\t\t cos\t\t tangent");
for(angle=0;angle<=180;angle+=10)
{
radian=(pi/180.0)*angle;
printf("\n%0.0f\t%f\t%f\t%f\t%f",angle,radian,sin(radian),cos(radian),tan(radian));
}
getch();
}
