Print a matrix in z form

Posted on Apr 26, 2020

C program to print a matrix in z form.

Z form is only defined in square matrices.

Program

#include<stdio.h>
#include<conio.h>
#define MAX 10

void read_matrix(int mat[MAX][MAX], int row, int col)
{
    int i, j;
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            printf("Element [%d][%d]\t:",i,j);
            scanf("%d",&mat[i][j]);
        }
    }
}

void print_matrix(int mat[MAX][MAX], int row, int col)
{
    int i, j;
    for(i=0;i<row;i++)
    {
        for(j=0;j<col;j++)
        {
            printf("%d\t",mat[i][j]);
        }
        printf("\n");
    }
}

void print_zpattern(int mat[MAX][MAX], int row)
{
    int i;

    for(i=0;i<row-1;i++)
    {
        printf("%d  ",mat[0][i]);
    }

    for(i=row-1;i>=0;i--)
    {
        printf("%d  ",mat[row-i-1][i]);
    }

    for(i=1;i<row;i++)
    {
        printf("%d  ",mat[row-1][i]);
    }
}

void main()
{
    int mat[MAX][MAX];
    int row, col;

    printf("Enter the number of rows or columns of the square matrix\t:");
    scanf("%d",&row);
    col = row;

    printf("Enter the elements of the matrix\n");
    read_matrix(mat, row, col);

    printf("\nMatrix entered is\n");
    print_matrix(mat, row, col);

    printf("\nMatrix in the Z form is\n");
    print_zpattern(mat, row);

    getch();
}

Output

Enter the number of rows or columns of the square matrix        :5
Enter the elements of the matrix
Element [0][0]  :1
Element [0][1]  :2
Element [0][2]  :3
Element [0][3]  :4
Element [0][4]  :5
Element [1][0]  :6
Element [1][1]  :7
Element [1][2]  :8
Element [1][3]  :9
Element [1][4]  :12
Element [2][0]  :23
Element [2][1]  :34
Element [2][2]  :45
Element [2][3]  :56
Element [2][4]  :67
Element [3][0]  :78
Element [3][1]  :89
Element [3][2]  :90
Element [3][3]  :11
Element [3][4]  :21
Element [4][0]  :32
Element [4][1]  :43
Element [4][2]  :54
Element [4][3]  :65
Element [4][4]  :76

Matrix entered is
1       2       3       4       5
6       7       8       9       12

32      43      54      65      76

Matrix in the Z form is
1  2  3  4  5  9  45  89  32  43  54  65  76
