There's no such thing as array[3.14159]. It has to be a whole integer. So floating point numbers as array indexes make no sense.

You could make k an integer, and it'd spew warnings, but it'd work. Using pow() is severe overkill, though -- your numbers are already binary. Just use binary operators to get at the bits in num instead of converting to float, doing exponents, and converting back.

Code:
#include <iostream>
#include <cmath>
using namespace std;

int main(void)
{
	unsigned int num, q;
	cout << "Enter a decimal number: " ; 
		cin >> num;

        for(q=31; q >= 0; q--)
        {
                // Shift the number q bits to the right, then check if bit 1 is set.
                if((num >> q) & 1) cout << "1";
                else                     cout << "0";
        }

        return(0);
}

NAME
XmRepTypeRegister -- A representation type manager function that registers a representation type resource SYNOPSIS
#include <Xm/RepType.h> XmRepTypeId XmRepTypeRegister( String rep_type, String *value_names, unsigned char *values, unsigned char num_values); DESCRIPTION
XmRepTypeRegister registers a representation type resource with the representation type manager. All features of the representation type management facility become available for the specified representation type. The function installs a forward type converter to convert string values to numerical representation type values. When the values argument is NULL, consecutive numerical values are assumed. The order of the strings in the value_names array determines the numerical values for the resource. For example, the first value name is 0 (zero); the second value name is 1; and so on. If it is non-NULL, the values argument can be used to assign values to representation types that have nonconsecutive values or have dupli- cate names for the same value. Representation types registered in this manner will consume additional storage and will be slightly slower than representation types with consecutive values. A representation type can only be registered once; if the same representation type name is registered more than once, the behavior is unde- fined. The function XmRepTypeAddReverse installs a reverse converter for a registered representation type. The reverse converter takes a represen- tation type numerical value and returns the corresponding string value. If the list of numerical values for a representation type contains duplicate values, the reverse converter uses the first name in the value_names list that matches the specified numeric value. For example, if a value_names array has cancel, proceed, and abort, and the corresponding values array contains 0, 1, and 0, the reverse converter will return cancel instead of abort for an input value of 0. rep_type Specifies the representation type name. value_names Specifies a pointer to an array of value names associated with the representation type. A value name is specified in lowercase characters without an Xm prefix. Words within a name are separated with underscores. values Specifies a pointer to an array of values associated with the representation type. A value in this array is associated with the value name in the corresponding position of the value_names array. num_values Specifies the number of entries in the value_names and values arrays. RETURN
Returns the identification number for the specified representation type. RELATED
