x = x + 1;
This statement assigns to `x` the value of `x` + 1:
gets the old value of `x`, then adds 1 to it, then stores the new value in `x` again.
This operation can also be done using the increment operator.
x++;
#include <iostream>
using namespace std;
int main() {
double a, b, c, d, e, f;
cin >> a >> b >> c >> d >> e >> f;
int counter = 0;
if (a > 0) {
counter++;
}
if (b > 0) {
counter++;
}
if (c > 0) {
counter++;
}
if (d > 0) {
counter++;
}
if (e > 0) {
counter++;
}
if (f > 0) {
counter++;
}
cout << counter << " valores positivos" << endl;
return 0;

INITIALIZATION: What to do before starting the loop?
CONDITION: What is the condition to continue looping?
ASSIGNMENT: What to do after each iteration?
