```
#include <iostream>
#include <cmath>
using namespace std;
const float G = 32.17;
// function declaration
float caltime ( float,float, float );
float calheight ( float,float,float);
// main function
int main()
{
float theta, cotheta, sitheta, distance, velocity, time, height;
cout << " Input the angle of elevation : " << endl;
cin >> theta;
cotheta = cos(theta);
sitheta = sin (theta);
cout << " Input the distance : " << endl ;
cin >> distance;
//use function
time = caltime ( distance,velocity, cotheta);

cout << " The flight will reach in the target within"<< time << "second " << endl;
cout << " The height will be " << height << "ft above the ground" << endl;
system ("pause");
return 0;
}
float caltime ( float x, float y, float z)
{
float timefind;
timefind = x/(y * z);
return timefind;
}
float calheight (float a,float b, float c)
{
float heightfind;
heightfind = ( a * b * c - (G * c*c /2)) ;
return heightfind;
}
```

Input the angle of elevation :

0.3

Input the distance :

1000

The flight will reach in the target within1.#INFsecond

The height will be -1.#INDft above the ground

Press any key to continue . . .

the result should not be like that, rite? how can I fix it
