using namespace std;
int main () {
double valor, desconto;
cout << "Digite o valor: ";
cin >> valor;
desconto = valor - ((valor * 25) / 100);
cout << "\n";
cout << "O valor com desconto de 25%: " << desconto << endl;

just a small note:
You did not count the discount (nor stored it in the variable `discount`). What you calculated and stored (and printed to the user) is the discounted value. Your calculation is correct, but your naming of things is not.
discounted value = original value - discount
