C++ Program to Compute Cross Product of Two Vectors

This is a C++ Program to find the cross product of two vectors. In mathematics, the cross product or vector product is a binary operation on two vectors in three-dimensional space. It results in a vector that is perpendicular to both and therefore normal to the plane containing them.

Here is source code of the C++ Program to Compute Cross Product of Two Vectors. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

```
#include<time.h>
```
```
#include<stdlib.h>
```
```
#include<iostream>
```
```
#include<math.h>
```
```
 
```
```
using namespace std;
```
```
const int LOW = 0;
```
```
const int HIGH = 10;
```
```
int main(int argc, char **argv)
```
```
{
```
```
    time_t seconds;
```
```
    time(&seconds);
```
```
    srand((unsigned int) seconds);
```
```
 
```
```
    int u1, u2, u3, v1, v2, v3;
```

    u1 = rand() % (HIGH - LOW + 1) + LOW;

    u2 = rand() % (HIGH - LOW + 1) + LOW;

    u3 = rand() % (HIGH - LOW + 1) + LOW;

    v1 = rand() % (HIGH - LOW + 1) + LOW;

    v2 = rand() % (HIGH - LOW + 1) + LOW;

    v3 = rand() % (HIGH - LOW + 1) + LOW;

```
 
```
```
    int uvi, uvj, uvk;
```
```
    uvi = u2 * v3 - v2 * u3;
```
```
    uvj = v1 * u3 - u1 * v3;
```
```
    uvk = u1 * v2 - v1 * u2;
```
```
 
```

    cout << "The cross product of the 2 vectors \n u = " << u1 << "i + " << u2

            << "j + " << u3 << "k and \n v = " << u1 << "i + " << u2 << "j + "

```
            << u3 << "k \n ";
```

    cout << "u X v : " << uvi << "i +" << uvj << "j+ " << uvk << "k ";

```
    return 0;
```
```
}
```

Output:

$ g++ CrossProduct.cpp
$ a.out
 
The cross product of the 2 vectors 
 u = 6i + 9j + 9k and 
 v = 6i + 9j + 9k 
 u X v : 0i +6j+ -6k
