Нужно перевести cout/cin в printf/scanf - C++
#include
#include
using namespace std;

int main() {
float a_1, a_2, a_3, x;
cout << "vvod a_1, a_2, a_3" << endl;
cin >> a_1 >> a_2 >> a_3;
cout << "Proizved " << a_1*a_2*a_3 << endl;
cout << "Sred geometr" << pow (a_1*a_2*a_3, 1./3) << endl;

cout << "vvod x" << endl;
cin >> x;
cout << "Po form:" << exp(1/(3*x))-abs(3*x*x-pow(pow(x+1,4) +log((pow(x,4)+4)/(pow(x,2)+2)), 1./5)) << endl;

int a;
cout << "vvod a" << endl;
cin >> a;
int c=a%10*10+a/10;
cout << c << endl;
system ("pause");
}
