Transfering a 2-dimensional array into a single dimension array

Question

I'm trying to make a program in C that transfers a 2-dimensions-array(a matrix to be particular) into a single-dimension-array. For example, if we have a matrix with L lines and C columns, it should turn into a a single line newL=L*C. Therefore, if the matrix has 3 lines and 4 columns, the new array will have 3*4=12 as its size.

The matrix should turn to this:

1 2
     --> 1 2 3 4
3 4 

The problem I'm facing right now, is how to assign the matrix to the array without having random values or repeated values.

The piece of code I'm concerned with, goes like this:

for(k=1;k<=t;k++)
    {
        for(i=1;i<=l;i++)
        {
            for(j=1;j<=c;j++)
            {
                v[k]=m[i][j];
            }
        }
    }

k,i and j are counters of the matrix(2-dimensions-array) and the the array. two of which; i and j, are counters for the matrix and k is the array's counter. Notice that each one of them starts from 1 and goes to its size and in this size I will use 2 lines and 2 columns for the matrix therefore the array will have a size of 4(2*2).

• l is the number of lines in the array.
• c is the number of colunms in the array.
• t is the size of the array. t=l*c

Executing the code gives me this as a return:

1 2
    --> 4 4 4 4
3 4

Simply said, the piece of code will ALWAYS give the last value of the matrix to the array. So if I replace 4 with 5 in the matrix, the array will have 5 5 5 5.

EDIT:

Here is the full code to understand what I'm trying to do:

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int c,i,j,l,k,t;
    printf("Donner le nombres des lignes: ");
    scanf("%d",&l);
    printf("Donner le nombres des colonnes: ");
    scanf("%d",&c);
    int m[l][c];
    t=l*c;
    int v[t];
    for(i=0;i<l;i++)
    {
        for(j=0;j<c;j++)
        {
            printf("Donner m[%d][%d]: ",i+1,j+1);
            scanf("%d",&m[i][j]);
        }
    }
    for(i=0;i<l;i++)
    {
        for(j=0;j<c;j++)
        {
            printf("%d\t",m[i][j]);
        }
        printf("\n");
    }
    printf("\n\n\n\n");
    for(k=1;k<=t;k++)
    {
        for(i=1;i<=l;i++)
        {
            for(j=1;j<=c;j++)
            {
                v[k]=m[i][j];
            }
        }
    }
    for(k=0;k<t;k++)
    {
        printf("%d\t",v[k]);
    }
    system("pause");
}

Thank you guys for the help, I found the correct way to do it.

Answer 1

1. You need not the outer loop
2. Array indices are zero-based in C

Thus, we have:

    for(k = 0, i = 0; i < o; i++)
    {
        for(j = 0; j < p; j++)
        {
            v[k++] = m[i][j];
        }
    }

where o and p - dimensions of the matrix m
