Rotating two dimensional array of integers

I have a problem with a task for my IT school. The problem is : Turn the frame of an array to left. Input : First get the numbers of tests (t). Then for each test get l and k (line and column), 3 <= l, k <= 100. Then fill the matrix with numbers from user.

Input:
1
3 3
1 2 3
4 5 6 
7 8 9 

Output:
2 3 6 
1 5 9
4 7 8 

My code so far :

#include<iostream>
#include<cstdio>
#include<cstdlib>

int main()
{
    int t, w, k;
    int tab[101][101];
    int t1[101], t2[101], t3[101], t4[101];
    scanf_s("%d", &t);
    for (int i = 0; i < t; i++) {
        scanf_s("%d %d", &w, &k);
        for (int j = 0; j < w; j++) {
            for (int x = 0; x < k; x++) {
                scanf_s("%d", &tab[j][x]);
                if (j == 0) {                   //1 linia
                    t1[x] = tab[j][x];          
                }
                if (j + 1 == w) {               //3 linia
                    t2[x] = tab[j][x];
                }
                if (x == 0) {                   //2 linia
                    t3[j] = tab[j][x];
                }
                if (x + 1 == k) {               //4 linia
                    t4[j] = tab[j][x];
                }
            }
        }
    printf("\n");
    }

    for (int j = 0; j < w; j++) {
        for (int x = 0; x < k; x++) {

            if (j == 0) {
                if (x == 0) {
                    tab[j][x] = t3[1];
                }
                else if (x + 1 != k-1) {
                    tab[j][x] = t1[j + 1];
                }
                else if (x + 1 == k-1) {
                    tab[j][x] = t4[1];
                }
            }
            if (j + 1 == w) {
                if (x == 0) {
                    tab[j][x] = t3[k - 2];
                }
                else if (x + 1 == k - 1) {
                    tab[j][x] = t4[w-2];
                }
                else if (x + 1 != k-1) {
                    tab[j][x] = t2[x + 1];
                }
            }
        }
    }

    for (int j = 0; j < w; j++) {
        for (int x = 0; x < k; x++) {
            printf("%d ", tab[j][x]);
        }
        printf("\n");
    }
    printf("\n");
    system("pause");
    return 0;
}

I know i'm doing the repositioning wrong. I tried it for like 5 different ways now. If anyone would show me a way of iterating through the table moving values to the left. I would be grateful. Also have in mind that l dont have to be equal to k.

You marked the question with C++ tag though I do not see neither C++ except some unused headers.:)

So I have written my demonstrative program In C.

If I have understood correctly you need something like the following. Only I have not entered values of the array. The array is set initially.

#include <stdio.h>

#define N   3

int main( void ) 
{
    int a[N][N] =
    {
        { 1, 2, 3 },
        { 4, 5, 6 },
        { 7, 8, 9 }
    };
    size_t i;

    for ( i = 0; i < N; i++ )
    {
        size_t j;
        for ( j = 0; j < N; j++ ) printf( "%d ", a[i][j] );
        printf( "\n" );
    }

    printf( "\n" );

    int tmp = a[0][0];

    for ( i = 1; i < N; i++ ) a[0][i-1] = a[0][i];
    for ( i = 1; i < N; i++ ) a[i-1][N-1] = a[i][N-1];
    for ( i = 1; i < N; i++ ) a[N-1][N-i] = a[N-1][N-i-1];
    for ( i = 1; i < N - 1; i++ ) a[N-i][0] = a[N-i-1][0];
    a[N-i][0] = tmp;

    for ( i = 0; i < N; i++ )
    {
        size_t j;
        for ( j = 0; j < N; j++ ) printf( "%d ", a[i][j] );
        printf( "\n" );
    }

    return 0;
}

The output is

1 2 3 
4 5 6 
7 8 9 

2 3 6 
1 5 9 
4 7 8 

If it is what you need then you can modify the program according to your requirements.:)
