C++ Program to Find maximum element of each row in a matrix
Given a matrix, the task is to find the maximum element of each row.
Examples:
Input : [1, 2, 3]
[1, 4, 9]
[76, 34, 21]
Output :
3
9
76
Input : [1, 2, 3, 21]
[12, 1, 65, 9]
[1, 56, 34, 2]
Output :
21
65
56
Approach : Approach is very simple. The idea is to run the loop for no_of_rows. Check each element inside the row and find for the maximum element. Finally, print the element.
Below is the implementation :
C++
// C++ program to find maximum // element of each row in a matrix#include<bits/stdc++.h>using namespace std;const int N = 4; // Print array element void printArray(int result[], int no_of_rows) { for (int i = 0; i < no_of_rows; i++) { cout<< result[i]<<""; } } // Function to get max element void maxelement(int no_of_rows, int arr[][N]) { int i = 0; // Initialize max to 0 at beginning // of finding max element of each row int max = 0; int result[no_of_rows]; while (i < no_of_rows) { for (int j = 0; j < N; j++) { if (arr[i][j] > max) { max = arr[i][j]; } } result[i] = max; max = 0; i++; } printArray(result,no_of_rows); } // Driver code int main() { int arr[][N] = { {3, 4, 1, 8}, {1, 4, 9, 11}, {76, 34, 21, 1}, {2, 1, 4, 5} }; // Calling the function maxelement(4, arr); } // This code is contributed by Rajput-Ji |
Output :
8 11 76 5
