C Slope finder returning weird numbers -

in c, attempting create program finds slope in effort learn more language. have created 6 variables hold needed information:

//variables  int one_x; int one_y;  int two_x; int two_y;  float top_number; float bottom_number; 

then, created way user enter information.

printf("------------------\n");  printf("enter first x coordinate.\n"); printf(">>>  \n"); scanf("%d", &one_x);  printf("enter first y coordinate.\n"); printf(">>>  \n"); scanf("%d", &one_y);   printf("------------------\n");  printf("enter second x coordinate.\n"); printf(">>>  \n"); scanf("%d", &two_x);  printf("enter second y coordinate.\n"); printf(">>>  \n"); scanf("%d", &two_y); 

lastly, program solves problem , displays answer.

bottom_number = two_x-one_x;  top_number = two_y - one_y;  printf ("the slope %d/%d", top_number, bottom_number); 

but, whenever run returns strange numbers:

1606415936/1606415768 

why this?

i using xcode , #include <stdio.h>

top_number , bottom_number declared float try print them int (the %d format specifier tells printf interpret argument type int). int , float have different sizes , bit representations doesn't work.

there number of options fix this. change them int

int top_number; int bottom_number; 

or change format specifiers in final printf %f

printf ("the slope %f/%f", top_number, bottom_number); 

or cast values in printf

printf ("the slope %d/%d", (int)top_number, (int)bottom_number); 

note there no benefit in using float unless may need represent fraction. isn't possible here you're subtracting 2 ints. calculation of slope (top_number/bottom_number) should treated float.

finally, hmjd earlier mentioned, should check return value scanf make sure have read int after each call

while (scanf("%d", &one_y) != 1); // repeat pattern each scanf call
