Question

A matrix is the rectangular array of numbers. Write a program to input and display a matrix of size m x n, where m is the number of rows and n is the number of columns of the matrix.

For example matrix of size 3 x 4 should display like this:

Source Code

#include <stdio.h>

int main()
{
    int i, j, m, n;
    int matrix[10][20];

    printf("Enter number of rows : ");
    scanf("%d", &m);
    printf("Enter number of columns : ");
    scanf("%d", &n);

    /* Input data in matrix */
    for (i = 0; i < m; i++)
    {
        for (j = 0; j < n; j++)
        {
            printf("Enter data in [%d][%d]: ", i, j);
            scanf("%d", &matrix[i][j]);
        }
    }

    /* Display the matrix */
    for (i = 0; i < m; i++)
    {
        for (j = 0; j < n; j++)
        {
            printf("%d\t", matrix[i][j]);
        }
        printf("\n");
    }

    return 0;
}

Output
