PHP Code:

```
/* program to perform martix addition */
```

# include <stdio.h>

void main ()

{

int i,j;

int a[2][2],b[2][2],c[2][2];

printf("\nAddition of A & B martices");

printf("\n\n Enter elements of martix A");

for (i=0;i<=1;i++)

{

for (j=0;j<=1;j++)

{

scanf("%d",&a[i][j]);

}

}

Printf("\nEnter elements of matrix B");

for (i=0;i<=1;i++)

{

for (j=0;j<=1;j++)

{

scanf("%d",&b[i][j]);

}

}

for (i=0;i<=1;i++)

{

for (j=0;j<=1;j++)

c[i][j]=a[i][j]+b[i][j];

}

printf(" Addition matrix of %d and %d is %d",a[2][2],b[2][2],c[2][2]);

printf("\n");

}

I'm getting errors. can you help me out.

Its 2 x 2 matrix addition, where A and B 2D arrays are taken as inputs and C arrays is output ( addition matrix of A and B)
