Thread: STL Stack problem

I have defined a stack from the STL like this:

Code:

stack<char> cStack;

Now I use this stack in an algorithm to convert a decimal number to hexadecimal format. This is the algorithm I have.

Code:

void decToHex(int num){
	int showNum = num;
	int storeNum;
	
	while(num != 0){
		storeNum = num % 16;
		switch(storeNum){
			case 10:
				cStack.push('A');
				break;
			case 11:
				cStack.push('B');
				break;
			case 12:
				cStack.push('C');
				break;
			case 13:
				cStack.push('D');
				break;
			case 14:
				cStack.push('E');
				break;
			case 15:
				cStack.push('F');
				break;
			default:
				cStack.push(storeNum);
				break;
		}
		num = num / 16;
	}
	
	cout << showNum << " in hexadecimal is ";
	while(!cStack.empty()){
		cout << cStack.top();
		cStack.pop();
	}
}

The program this algorithm belongs to compiles fine and runs great but the problem is that since the type of the stack is of a char type, it converts the default case into an ASCII value and doesn't print the number like I need it to. Any suggestions on how to correct this?

Another question is I had an idea of making the stack dual types using a union that had an integer and char in it. Is this a legitimate idea?
