I have attached the original problems and below is what I have started. It compiles with this warning "geometry.c:9: warning: built-in function 'y1' declared as non-function" help please. . Thanks!
Code:
#include <stdio.h>
/* Function Prototypes */
int a;
double m, x1, x2, y1, y2;
int get_problem (int a);
double get2_pt (double x1, double x2, double y1, double y2);
double get_pt_slope (double m, double x1 , double y1);
/*double slope_intcpt_from2_pt
double intcpt_from_pt_slope
double display2_pt
double display_pt_slope
double display_slope_intcpt*/
int main (void)
{
get_problem (a);
return (0);
}
int get_problem (int a)
{
printf("Select the form that you would like to convert to slope-\n");
printf("intercept form:\n");
printf("1) Two-point form (you know two points on the line)\n");
printf("2) Point-slope form (you know the line's slope and one point)\n");
printf("=>");
scanf("%d", &a);
if (a==1) {
get2_pt (x1, x2, y1, y2);
}
else if (a==2) {
get_pt_slope (m, x1, y1);
}
}
double get2_pt (double x1, double x2, double y1, double y2)
{
printf("Enter the x-y coordinates of the first point separated by a");
printf("space=> ");
scanf("%lf %lf", &x1, &y1);
printf("Enter the x-y coordinates of the second point separated by a");
printf("space=> ");
scanf("%lf %lf", &x2, &y2);
}
double get_pt_slope (double m, double x1, double y1)
{
printf("Enter the slope=> ");
scanf("%lf", &m);
printf("Enter the x-y coordinates of the point separated by a space=> ");
scanf("%lf %lf", &x1, &y1);
}
