where is my wrong in function in function

[Ph0x]

i want to check geo_analyzer using by check_line and check_triangle thank you for appreciated answers

double calculateSlop(double a,double b,double c,double d){

    return (d-c)/(b-a); // like (y2-y1)/(x2-x1)
}

int geo_analyzer( double p1_x, double p1_y, double p2_x, double
    p2_y, double p3_x, double p3_y, double p4_x, double p4_y){

        double m1,m2,m3;

        m1=calculateSlop(p1_x,p2_x,p1_y,p2_y);
        m2=calculateSlop(p2_x,p3_x,p2_y,p3_y);
        m3=calculateSlop(p3_x,p4_x,p3_y,p4_y);

        if(check_line==1){
        return 1; // line
        }
        if(check_triangle==1){
        return 2; //triangle
    }
}

}

What exactly is your problem, what is not working as it is supposed to?

i get the error /home/soner/Untitled1.c|60|warning: comparison between pointer and integer [enabled by default]|

 if(check_line==1){       
return 1; // line
     
        if(check_triangle==1)
        return 2; //triangle

If you want to call function 'check_line' and 'check_triange' you have to do it like:

if ((check_line(/* insert your arguments here*/ ) == 1)) {
 
    /* blah blah blah */

}
