So I'm on university doing 3th grade of computer sciende (a 4 year career) but I have no idea on how to code so it was actually quite hard for to me to pass this semester (who would have thougth!?).
Becouse of this I decided to start learning C again, I did learn to code in pseudocode and C in first year but forgot how to.
Today I was trying to make an algorithm that would return all the A, B, and C variables (all between 0 and 9) such that (10A+B)/(10B+C)=A/C becouse the solutions are nice and I had already solved the equation by hand and already knew all the solutions. But I just can't make it work, I'm using an online C compiler and it doesn't show any error so I guess it's stuck in a loop.
This is my sloppy code;

Code:
#include <stdio.h>


int
main ()
{
    int a, b, c, d, e;
    while (a + b + c != 27)
    a = 0;
    b = 0;
    c = 0;
    a = a++;
        if (a = 9)
        a = 0;
        b = b + 1;
            if (b = 9)
            c = c++;
            d = (10 * a + b) / (10 * b + c);
            e = a/c;
                if(d=e)
                printf ("%d",a);
                printf ("%d",b);
                printf ("%d",c);
    return 0;
}


Thanks!
