syntax - Error in job Build for constructing C++ program to determine range -


i till experiencing issues until made change formula gravity. working now. everyone. appreciate great feedback

    #include <iostream>     #include <string>     #include <cstdlib>     #include <cmath>      using namespace std;      int main()     {         // initialize objects:              double angle = 0.0;         double velocity = 0.0;          double range = 0.0;         const double pi = 3.141592653589793238;         const double gravity = 9.8; //meters pers second          // input:          cout << "takeoff angle: ";         cin >> angle;         cout << "please enter velocity: ";         cin >> velocity;          // process          angle = angle * pi / 180;         range = sin(2 * angle) * velocity * velocity / gravity;          cout << " range " << range << endl;         system("pause");          return 0;  } 

range = sin(* angle)*velocity pow(2);

this not valid c++.

pow function takes 2 arguments. x^y represented pow(x, y).

also, sin(*angle) invalid angle neither pointer nor class defined * operator.

i think you're looking for:

range = sin(2 * angle) * velocity * velocity / gravity; // (no need use pow(velocity, 2) on velocity * velocity)

(this correct formula range)

SPSS keyboard combination alters encoding -

my question not have programming practical issue on spss. accident keyword combination cannot remember because did not intend press changed encoding in spss , text in data in different language english shown small boxes. nevertheless, when kind of analysis performed different language text shown in output. does know reason? tried change encoding did not produce result. first, @ edit > options , see whether setting unicode or locale. might fix it. if have text in multiple languages, want unicode. otherwise, may have specific locale set wrong. can change set locale, need know locale want use.
