 Posted: Wed Jul 30, 2008 10:52 pm Post subject: [C++] Converting hex to decimal? |
 |
|
it's kinda hard to explain this but its like this:
my program reads a value for a pointer
i use a label to show the value
when the value is a negative it's like 4,XXX,XXX,XXX(its the number where you hex the negative value and make it back into a decimal value)
What i want to do is make it so then it wouldnt show the 4 billion value but show the negative value instead.  help please |

| In your case, check on wsprintf() |

| Code: | #include <iostream>
int main( void )
{
char text[128];
int number;
printf("Which number do you want to convert to hex? ");
std::cin >> number;
sprintf(text,"%x",number);
printf("%d is %s in hex.\n",number,text);
std::cin.get();
std::cin.get();
} |
That's what I found some time ago, but you guys will probably say it's a bad way to do it or something... |

:P More of a C++ way: | Code: | #include <iostream>
int main(int argc, char *argv[])
{
int i;
std::cout << "Num: ";
std::cin >> i;
std::cout << "Hex: " << std::hex << i;
return EXIT_SUCCESS;
} |
std::hex works with stringstream and so on.. |

I was replying to Nuclear898 (that's why the quote.). Also the same stuff works the other way round too, if you're enough smart to understand that. Btw.. Int is a integer, hex is a representation of the integer. | Code: | #include <iostream>
int main(int argc, char *argv[])
{
int i;
std::cout << "Num: ";
std::cin >> std::hex >> i;
std::cout << "Dec: " << std::dec << i;
return EXIT_SUCCESS;
} |
| Code: | ./a.out
Num: A
