Question

Помогите с задачей по C++

Answer 1

Табулирование функции y=x^2 на интервале [-6, 6] с шагом 1:
1.
#include <iostream>
using namespace std;

int main() {
for (int x=-6; x<=6; x++)
  cout << "x = " << x << "  y = " << x*x << "n";
return 0;
}

2.
#include <iostream>
using namespace std;

int main() {
int x=-6;
while (x<=6) {
  cout << "x = " << x << "  y = " << x*x << "n";
  x += 1;
}
return 0;
}

3.
#include <iostream>
using namespace std;

int main() {
int x=-6;
 do {
  cout << "x = " << x << "  y = " << x*x << "n";
  x += 1;
}
while (x<=6);
return 0;
}

Результат:
x = -6 y = 36
x = -5 y = 25
x = -4 y = 16
...
x = 5 y = 25
x = 6 y = 36
