int main()
{
 
int A[3][3], B[3][3];
int i,j;
 
//INPUT of MATRIX/ 2D ARRAY A
printf("\n Enter the elements of matrix A: \n");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
{
scanf(" %d ", &A[i][j]);
}
}
 
//INPUT of MATRIX/ 2D ARRAY B
printf("\n Enter the elements of matrix B: \n");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
{
scanf(" %d ", &B[i][j]);
}
}
 
//ADDING THE TWO MATRICES
printf("\n Adding matrices A and B = matrix C ");
int C[3][3];
 
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
{
C[i][j]=A[i][j]+B[i][j];
}
}
 
//OUTPUT
printf("\n Matrix C is: \n");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
{
printf(" %d ", C[i][j]);
}
printf("\n");
}
 
return 0;
}
 

OUTPUT:

 Enter the elements of matrix A: 
1 2 3
1 2 3
3 2 1

 Enter the elements of matrix B: 
3 2 1
3 2 1
1 2 3

 Adding matrices A and B = matrix C 
 Matrix C is: 
 4  4  4 
 4  4  4 
 4  4  4
