how will you convert a hexadecimal ABC into its octal and decimal equivalent ?

 #include

#include

void main()

{

int a,b,c;

int h=16,i=8,j=10;

long e,f,g;

long m,n,o,p;// modulas

long u,v,x,y,z;//dividing

clrscr();

printf("\n\t The Hexadecimal Value is\t:\tABC");

a=10;

b=11;

c=12;

e=a+(b*h)+(c*h*h);

printf("\n\n\t the decimal value is\t\t:\t%ld",e);

f=e/i;

m=e%i;

n=f/i;

u=f%i;

x=u/i;

o=u%i;

printf("\n\n\t The Octal value is\t\t:\t%d%d%d",m,u,o);

getch();

}
