Determinant matrix calculating in C through pipe function. revision code

[enemy]

Hi guys. Need to develop a program is performed using IPC mechanisms one of the following problems: The way - "Channels." Implement the computation of the determinant of a square matrix by expanding it on the determinants of lower order. The "master" process sends the job "driven" processes but the latter perform a calculation of determinants, and then calculates the result of the main process. In other words, need to use the pipe function. I have a working program but without IPC mechanisms. I don't know about pipe function and how it's working. Help please

#include<stdio.h>
#include<math.h>
#include<stdlib.h>
 
int determinant(int n, double mat[n][n])
{
    int i,j,i_count,j_count, count=0;
    double array[n-1][n-1], det=0;
    if(n==1) return mat[0][0];
    if(n==2) return (mat[0][0]*mat[1][1] - mat[0][1]*mat[1][0]);
 
    for(count=0; count<n; count++)
    {
        i_count=0;
        for(i=1; i<n; i++)
        {
            j_count=0;
            for(j=0; j<n; j++)
            {
                if(j == count) continue;
                array[i_count][j_count] = mat[i][j];
                j_count++;
            }
            i_count++;
        }
        det += pow(-1, count) * mat[0][count] * determinant(n-1,array);
    }
    return det;
}
 
int main()
{
    int i, j, dim;
    printf(" Enter n\n");
    scanf("%d", &dim);
    double matrix[dim][dim];
    printf("Enter matrix:\n");
    for(i = 0; i < dim; i++)
    {
        for(j = 0; j < dim; j++)
        {
            scanf("%lf \n", &matrix[i][j]);
        }
    }
    double x = determinant(dim, matrix);
    printf("Determinant = %g\n", x);
    return 0;
}

For *nix you could look at Beej's Guide to Unix IPC.
