### Program 128:To get difference of 'N' Matrices

Program 128:

```#include<stdio.h>
main()
{
int i,j,rows,col,flag=1,x;
printf("Enter number of rows\n");
scanf("%d",&rows);
printf("Enter number of columns\n");
scanf("%d",&col);
int a1[rows][col],a2[rows][col],diff[rows][col];
//Taking input for 1st matrix
printf("Enter Matrix 1\n");
for(i=0;i<rows;i++)
{
for(j=0;j<col;j++)
{
scanf("%d",&a1[i][j]);
}
}
do
{
//Taking input for 2nd matrix
printf("Enter Matrix 2\n");
for(i=0;i<rows;i++)
{
for(j=0;j<col;j++)
{
scanf("%d",&a2[i][j]);
}
}
//Difference of matrix
for(i=0;i<rows;i++)
{
for(j=0;j<col;j++)
{
diff[i][j]=a2[i][j]-a1[i][j];
}
}

for(i=0;i<rows;i++)
{
for(j=0;j<col;j++)
{
printf("%d\t",diff[i][j]);
}
printf("\n");
}
printf("Enter 1 to continue to subtract the above from another matrix else 0\n ");
scanf("%d",&x);
if(x==1)
{
flag=1;
for(i=0;i<rows;i++)
{
for(j=0;j<col;j++)
{
a1[i][j]=diff[i][j];
diff[i][j]=0;
}
}
}
else
{
flag=0;
}

}while(flag);

printf("The final Difference of matrices is\n");

for(i=0;i<rows;i++)
{
for(j=0;j<col;j++)
{
printf("%d\t",diff[i][j]);
}
printf("\n");
}
}
