Program in C

Here is the source code of the C Program to print the square of each element of the 2d array or matrix.

Code:

#include<stdio.h> #include<math.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 square of the matrix for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { matrix[i][j]=pow(matrix[i][j],2); } } //display square of the matrix printf("Square of the Matrix elements are:\n"); for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { printf("%d ",matrix[i][j]); } printf("\n"); } }

Input/Output:

Enter the row Size Of the Matrix:2 Enter the columns Size Of the Matrix:2 Enter the Matrix Element: 7 9 4 5 Square of the Matrix elements are: 49 81 16 25

Program in C++

Here is the source code of the C++ Program to print the square of each element of the 2d array or matrix.

Code:

#include<iostream> #include<cmath> 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 square of the matrix for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { matrix[i][j]=pow(matrix[i][j],2); } } //display square of the matrix cout<<"Square of the Matrix is:\n"; for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { cout<<matrix[i][j]<<"\t"; } cout<<"\n"; } }

Input/Output:

Enter the row Size Of the Matrix:3 Enter the columns Size Of the Matrix:2 Enter the Matrix Element: 2 3 4 5 6 7 Square of the Matrix is: 4 9 16 25 36 49

Program in Java

Here is the source code of the Java Program to print the square of each element of the 2d array or matrix.

Code:

import java.util.Scanner; public class SquareOfTheMatrix { 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 square of the matrix for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { matrix[i][j]=(int) Math.pow(matrix[i][j],2); } } //display the square of the matrix System.out.println("Square of the Matrix elements are:"); for(i=0;i<row_size;i++) { for(j=0;j<col_size;j++) { System.out.print(matrix[i][j]+" "); } System.out.println(); } cs.close(); } }

Input/Output:

Enter the row Size Of the Matrix:3 Enter the columns Size Of the Matrix:3 Enter the Matrix Element: 4 5 6 7 8 9 2 3 4 Square of the Matrix elements are: 16 25 36 49 64 81 4 9 16   

Program in Python

Here is the source code of the Python Program to print the square of each element of the 2d array or matrix.

Code:

# 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 square of the matrix for i in range(0,row_size): for j in range(0,col_size): matrix[i][j]=pow(matrix[i][j],2) # display square of the matrix print("Square of the Matrix elements are:") for m in matrix: print(m)

Input/Output:

Enter the row Size Of the Matrix:2 Enter the columns Size Of the Matrix:3 Enter the Matrix Element: 4 5 6 7 8 9 Square of the Matrix elements are: [16, 25, 36] [49, 64, 81]
