Some how the "or" ( || ) did not work, or I just misunderstood it?? C++

Question

temp:
if (type == "f" || "F"){
conv = (temp - 32) * 5/9;
cout << temp << " degree fahrenheit is " << conv << " degree celsius" << endl;
getch();
system("CLS");
goto mainmenu;
}
if (type == "c" || "C"){
conv = (temp * 9/5) + 32;
cout << temp << " degree celsius is " << conv << " degree fahrenheit" << endl;
getch();
system("CLS");
goto mainmenu;
}
else{
cout << "Wrong input.";
getch();
system("CLS");
goto temp;
}
goto temp;

When I gave the "type" input as c or C, it somehow keep going with the first if. This only happens when I put the "||" symbol.

Answer 1

if(type == "f" || type == "F"), this should work.
if(condition1 OR condition2), in your case condition2 is just "F"

Answer 2

if(type == "c" || type == "C")

Answer 3

THANKS SO MUCH!! been struggling with this for 5 dayss

Answer 4

As above: It compares two boolean values.
It's not like in speech (It's F or f)
In programming, it's like: Is it F? Yes/No? And is it f?
And then it will give you yes or no.
