float var gives ?wrong? values in printf

[John]

I am going through the tutorial that comes with Dev-C++ 5 (beta). Everything was great right up to float variables.

int,and char work fine. But float and double work well untill I give them a value other than zero. In the code below, if I give a and b a value greater than zero, a printf's as 0 and b as 1072693248. Double does the same.

Am I trying to printf them incorecctly?

I tried uninstalling dev-C++ 5 and installing ver. 4. I'm back to five with a clean install and an install on another pc. All do the same trick.

Here is the code:

---

include <cstdlib>

include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
int one, two;
one=1;
two=2;
float a,b;
a=1;
b=2;
printf("var 'one' equals: -%d-, and var 'two' equals: -%d-\n",one, two);
printf("But Float var 'a' is %d (should be 1), and b is %d (should be 2)\n\n Why Why Why???\n\n",a,b);
system("PAUSE");
return EXIT_SUCCESS;
}

---

The output of this is:

var 'one' equals: -1-, and var 'two' equals: -2-
But Float var 'a' is 0 (should be 1), and b is 1072693248 (should be 2)

Why Why Why???

Press any key to continue . . .

end of output

I finally found the right question and asked the oracle, and google said "%f my son, %f"
