Thread: new to C - decimal to hexadecimal converter

hmmm, maybe i should try a different compiler, but i can't find a good one for vista, like i tried codeblocks mingw release but nothing would build for some reason, ugh this is so frustrating...

anyway
here's my code after all the modifications

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main() {
	union
	{
		int a;
		float b;
	}myUnion;

	printf("Enter the Decimal number to be converted:\n");

	scanf("%f",&myUnion.b);

	printf("The number in Hexadecimal is:\n");

	printf("%x",myUnion.a);
	
	
	while((myUnion.a = getchar()) != '\n'); //these two lines work to hold the console window open
    myUnion.a = getchar();
	
	return 0;
}

like i said when i input 13 it produces 41500000, weird

i get the same output, but its correct.
a float in memory has a different structure than an integer.

the printf("%x",int) means, take the 4 bytes at the ints address and treat them like they contain an int value but they don't.

I thought Memloop spelled out the trouble here:
new to C - decimal to hexadecimal converter

If you can give me an example of what you want, input and output. I'm sure I can help you get there. I will not use unions to do it, however. They are not required to do what you want and, (as you see here), can be a pain to work with.

You'll have to show me actual input and output or two or three, of what you want. I do not want a description only.

I'm idiot, i finally got it working, its still a little off but its not a big deal, thanks
