Matrix:
-Multidimensional Array
-Matrix consist of the rows and columns.
Syntax-
array[row][column]
//Matrix with numbers of rows and columns
Example-
Matrix is:
1 2
4 3
Sum of all elements in array is 10
program:
#include < iostream>
using namespace std;
int main()
{
int a[10][10],r,c,i,j,sum=0;
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];
}
}
//add all element of array
for(i=0;i< r;i++)
{
for(j=0;j< c;j++)
sum=sum+a[i][j];
}
cout<<"Sum of matrix is: "<< sum;
return 0;
}
Enter rows and column in matrix
2 3
Enter 6 number in matrix
1 2 3 4 5 6
Sum of Matrix is: 21
