This is a C Program to find the cross product of two vectors. 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 <string.h>
#include <stdio.h>
#include <stdlib.h>
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;
printf("The cross product of the 2 vectors \n u = %di + %dj + %dk and \n v = %di + %dj + %dk\n",
u1, u2, u3, v1, v2, v3);
printf(" u X v: %di + %dj + %dk", uvi, uvj, uvk);
return 0;
}
Output:
$ gcc CrossProduct.c $ ./a.out The cross product of the 2 vectors u = 0i + 0j + 7k and v = 4i + 7j + 2k u X v: -49i + 28j + 0k
