Matrix in C++ by R4R Team

Matrix:
-Multidimensional Array
-Matrix consist of the rows and columns.

Syntax-
array[row][column]
//Matrix with numbers of rows and columns

Example-
a[2][2]
//matrix with 2 rows and 2 columns

Input and traverse the matrix:

program:

#include< iostream>
int main()
{
int a[10][10],r,c,i,j;
cout<<"Enter rows and columns"<< endl;
cin>>r>>c;
//input in matrix
cout<<"Enter "<< r*c<<" number in matrix"<< endl;
for(i=0;i< r;i++)
{
for(j=0;j< c;j++){
cin>>a[i][j];
}
}
//Now traverse the matrix
cout<<"Matrix is"<< endl;
for(i=0;i< r;i++)
{
for(j=0;j< c;j++){
cout<< a[i][j]<<" ";
}
cout<< endl;
}
}

output-

Enter rows and columns
2 2
Enter 4 number in matrix
1 2 3 4
Matrix is
1 2
3 4

Enter rows and columns
3 3
Enter 9 number in matrix
1 2 3 4 5 6 7 8 9
Matrix is
1 2 3
4 5 6
7 8 9

-In this program, firstly we take a input of the numbers of rows and columns of matrix, then input in matrix.
-As matrix is two dimensional array so we require 2 loops for all kind of operation to perform on it.
