cout << “The Decimal Equivalent of the Binary Number is “;

cout << dec;

else

cout << “Not a Binary! Try another numbers between 0’s and 1’s only!”;

break;

}

case 2:

{

int num, i=1, bin=0;

cout << “Enter a Decimal Number: “;

cin >> num;

while (num!=0)

{

bin=bin+(num%2)*i;

i=i*10;

num=num/2;

}

cout << “The Binary Equivalent of the Decimal Number is “;

cout << bin;

break;

}

default:

cout << “That is Invalid!\n”;

break;

}

return 0;

}

Hi,

the main problem is that you are using “ instead of " ,

change it and see if it helps

if(res%10 == 0 || res%10 == 1) // <--
{ // <--
    cout << "The Decimal Equivalent of the Binary Number is ";
    cout << dec;
} // <--
