syntax?

ok so i have no idea what tags are i probably posted this wrong

i have no idead what i did wrong i know its probably simple but i have only been programming for a week

Code:

#include<iostream>
using namespace std;

int main(void)
{

	system("TITLE Calculator");
	system("COLOR 2");
	char cChar;
	double dfirstnumber;
	double dsecondnumber;
	char cDoagain;
	
do
{
	system("CLS");
	cout << "please enter the first number that you would like to use" << endl;
	cin >> dfirstnumber;
	cout << "please enter the operation that you would like to complete" << " (+,-,* or /)" << endl;
	cin >> cChar;
	cout << "please enter the second number you would like to use" << endl;
	cin >> dsecondnumber;
	
		switch (cChar)
		{
		case '+':
			cout << "the answer is; " << dfirstnumber << " + " << dsecondnumber << " = " << (dfirstnumber + dsecondnumber) << endl;
				break;
		case '-':
			cout << "the answer is; " << dfirstnumber << " - " << dsecondnumber << " = " << (dfirstnumber - dsecondnumber) << endl;
				break;
		case '*':
			cout << "the answer is; " << dfirstnumber << " * " << dsecondnumber << " = " << (dfirstnumber * dsecondnumber) << endl;
				break;
		case 'x':
			cout << "the answer is; " << dfirstnumber << " x " << dsecondnumber << " = " << (dfirstnumber x dsecondnumber) << endl;
				break;
		case 'X':
			cout << "the answer is; " << dfirstnumber << " X " << dsecondnumber << " = " << (dfirstnumber X dsecondnumber) << endl;
				break;
		case '/':
			if(dsecondnumber ==0) {
			cout << "that is an invalid operation" << endl;
			}else{
			cout << "The answer is; " << dfirstnumber << " / " << dsecondnumber << " = " << (dfirstnumber / dsecondnumber) << endl;
			}
		default:
			cout << "that is an invalid operation" << endl;
			break;
		}
		cout << "would you like to start again? (y or n)" << endl;
		cin >> cDoagain;
	}while (cDoagain == 'Y' || cDoagain == 'y');
	system("pause");
	return 0;
	
}

these are the errors if it helps

error C2146: syntax error : missing ')' before identifier 'x'
error C2059: syntax error : ')'
error C2146: syntax error : missing ')' before identifier 'X'
error C2059: syntax error : ')'

Well here is your error

Code:

(dfirstnumber x dsecondnumber)

of course you want * instead of x.

Next time double click on the error, usually it highlights the line it is on. Or look at the error message and go to that line. In any case, find the line where the error is. Then you should be able to figure it out more.

Why do I say that? Because I was looking for 'x' and 'X' in your code. I first show the ones after case. So I checked those, but they were ok. Did you do the same? If yes, then you should have followed my advice above when running through an IDE with a compiler (I guess you are using Visual Studio?), since you could have found out which line it is on exactly. Which in case you would look on that line for 'x'. Which would lead you right on the problem!

i did that but the error said missin ) before x so i thought x was fine i thought it meant i was missing ) before it? but any ways so i should delete one line and cahnge the other to * ?

when i run and divide a number it always says this is an invalid operation while running it?
i really new to programming like 2 days lol srry if it really stupid of me to ask
