#include <iostream>

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;

return 0;

}

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
