Thread: matrix addition program using arrays

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)

please, can you tell give me the correct code of the program.
How to indent the code.

// this is what I have changed it to, still I'm getting errors. can you give me the code of it please....

/* 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<2;i++)
{
for (j=0;j<2;j++)
{

scanf("%d",&a[i][j]);
}
}
Printf("\nEnter elements of matrix B");
for (i=0;i<2;i++)
{
for (j=0;j<2;j++)
{

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

for (i=0;i<2;i++)
{
for (j=0;j<2;j++)
c[i][j]=a[i][j]+b[i][j];

printf(" Addition matrix of %d and %d is %d",a[i][j],b[i][j],c[i][j]);
}
printf("\n");

}

ya I got it... thanks a lot.
