Program in C

Here is the source code of the C Program to find the maximum element in the matrix.

Code:

#include<stdio.h> #include<limits.h> int main() { int row_size,col_size; //Get size of matrix printf("Enter the row Size Of the Matrix:"); scanf("%d",&row_size); printf("Enter the columns Size Of the Matrix:"); scanf("%d",&col_size); int matrix[row_size][col_size]; //Taking input of the matrix int i,j; printf("Enter the Matrix Element:\n"); for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { scanf("%d",&matrix[i][j]); } } //compute the maximum element of the given 2d array int max=INT_MIN; for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { if(matrix[i][j]>=max) max=matrix[i][j]; } } //Display the largest element of the given matrix printf("The Maximum element of the Given 2d array is: %d",max); }

Input/Output:

Enter the row Size Of the Matrix:2 Enter the columns Size Of the Matrix:2 Enter the Matrix Element: 7 2 8 5 The Maximum element of the Given 2d array is: 8

Program in C++

Here is the source code of the C++ Program to find the maximum element in the matrix.

Code:

#include<iostream> using namespace std; int main() { int row_size,col_size; //Get size of matrix cout<<"Enter the row Size Of the Matrix:"; cin>>row_size; cout<<"Enter the columns Size Of the Matrix:"; cin>>col_size; int matrix[row_size][col_size]; //Taking input of the matrix int i,j; cout<<"Enter the Matrix Element:\n"; for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { cin>>matrix[i][j]; } } //compute the maximum element of the given 2d array int max=INT_MIN; for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { if(matrix[i][j]>=max) max=matrix[i][j]; } } //Display the largest element of the given matrix printf("The Maximum element of the Given 2d array is: %d",max); }

Input/Output:

Enter the row Size Of the Matrix:3 Enter the columns Size Of the Matrix:3 Enter the Matrix Element: 7 2 3 1 2 4 5 6 5 The Maximum element of the Given 2d array is: 7

Program in Java

Here is the source code of the Java Program to find the maximum element in the matrix.

Code:

import java.util.Scanner; public class FindMaximumElement { public static void main(String[] args) { Scanner cs=new Scanner(System.in); int row_size,col_size; //Get size of matrix System.out.print("Enter the row Size Of the Matrix:"); row_size=cs.nextInt(); System.out.print("Enter the columns Size Of the Matrix:"); col_size=cs.nextInt(); int matrix[][] =new int[row_size][col_size]; //Taking input of the matrix int i,j; System.out.println("Enter the Matrix Element:"); for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { matrix[i][j]=cs.nextInt(); } } //compute the maximum element of the given 2d array int max=Integer.MIN_VALUE; for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { if(matrix[i][j]>=max) max=matrix[i][j]; } } //Display the largest element of the given matrix System.out.println("The Maximum element of the Given 2d array is: "+max); cs.close(); } }

Input/Output:

Enter the row Size Of the Matrix:3

Enter the columns Size Of the Matrix:3

Enter the Matrix Element:

10 11 12

33 45 65

77 78 19

The Maximum element of the Given 2d array is: 78

Program in Python

Here is the source code of the Python Program to find the maximum element in the matrix.

Code:

import sys # Get size of matrix row_size=int(input("Enter the row Size Of the Matrix:")) col_size=int(input("Enter the columns Size Of the Matrix:")) matrix=[] # Taking input of the matrix print("Enter the Matrix Element:") for i in range(row_size): matrix.append([int(j) for j in input().split()]) #compute the maximum element of the given 2d array max=-sys.maxsize-1 for i in range(len(matrix)): for j in range(len(matrix[0])): if matrix[i][j]>=max: max=matrix[i][j] # Display the largest element of the given matrix print("The Maximum element of the Given 2d array is: ",max)

Input/Output:
