C Program to Display the Maximum Element of each row in a 2-D Matrix

  • In this problem, we are required to implement a program wherein we have to display the largest element in each row in a 2-D array.
  • First, we take a 2-Darray as an input from the user.
  • After that we compare each element of the array in a row to determine the largest element in each row and display it as output.
#include<stdio.h>
int main ()
{
    int i, j, r, c, n, a[100][100], max[100];
    printf ("Enter the number of rows: ");
    scanf ("%d", &r);
    printf ("Enter the number of columns: ");
    scanf ("%d", &c);
    printf ("Enter the elements of the array- \n");
    
    for (i = 0; i < r; i = i + 1)
    {
        for (j = 0; j < c; j = j + 1)
	    {
	        printf("[%d %d]: ", i + 1, j + 1);
	        scanf("%d", &a[i][j]);
	    }
    }
  
    printf ("The input matrix is:- \n");
    for (i = 0; i < r; i++)
    {
        for (j = 0; j < c; j++)
	    {
	        printf ("%d\t", a[i][j]);
	    }
        printf ("\n");
    }
  
    for (i = 0; i < r; i++)
    {
        max[i] = a[i][j];
        for (j = 0; j < c; j++)
	    {
	        if (a[i][j] > max[i])
	        {
	            max[i] = a[i][j];
	        }
	    }
    }
  
    for (i = 0; i < r; i++)
    {
        printf ("Maximum element of the row %d is: %d\n", i, max[i]);
    }
    return 0;
}
