Now i blog with many matters related to programming and also some thrilling programs mainly based on c and c++ ,now this particular c prg is to convert numbers to words eg:23698 to twenty three thousand six hundred ninty eight

int nested_flag = 1;

void push(int item)

printf("Number too big.Stack overflow.");
printf("Press any key to exit......");
getch();
exit(0);

}

else
