In this tutorial, i am going to show you how to find the maximum or largest element in each row on 2d array in c program..

## C Program and Algorithm To Find the Largest Element in a Row in 2d Array

- Algorithm To Find the Largest Element in Each Row in 2d Array
- C Program To Find the Largest Element in Each Row in 2d Array

### Algorithm To Find the Largest Element in Each Row in 2d Array

Just use the below given algorithm to write a program to find the maximum element in each row of the 2d array or matrix array; as follows:

- Start
- Declare a 2D array.
- Initialize the 2D array.
- Take input row and column count from user.
- Take input 2d array elements from user.
- Iterate the for loop to total number of rows.
- Check each element for the row and find the maximum element from it.
- Now print the elements.
- Stop.

### C Program To Find the Largest Element in Each Row in 2d Array

#include <stdio.h> int main() { int m,n; //Matrix Size Declaration printf("Enter the number of rows and column: \n"); scanf("%d %d",&m,&n); //Matrix Size Initialization int arr[10][10]; //Matrix Size Declaration printf("\nEnter the elements of the matrix: \n"); for(int i=0;i<m;i++) //Matrix Initialization { for(int j=0;j<n;j++) { scanf("%d",&arr[i][j]); } } printf("\nThe elements in the matrix are: \n"); for(int i=0;i<m;i++) //Print the matrix { for(int j=0;j<n;j++) { printf("%d ",arr[i][j]); } printf("\n"); } int i = 0, j; int max = 0; int res[m]; while (i < m) //Check for the largest element in an array { for ( j = 0; j < n; j++) { if (arr[i][j] > max) { max = arr[i][j]; } } res[i] = max; max = 0; i++; } for(int i = 0; i < n; i++) //Print the largest element in an array { printf("Largest element in row %d is %d \n", i, res[i]); } return 0; }

The result of the above c program; as follows:

Enter the number of rows and column: 3 3 Enter the elements of the matrix: 1 2 3 4 5 6 7 8 9 The elements in the matrix are: 1 2 3 4 5 6 7 8 9 Largest element in row 0 is 3 Largest element in row 1 is 6 Largest element in row 2 is 9
