void main()
{
int a[10][10],b[10][10],c[10][10],i,j,c1,r1,c2,r2,ir2;
printf("enter the row and column of 1st matrix");
scanf("%d%d",&r1,&c1);
printf("enter the row and column of 2nd matrix");
scanf("%d%d",&r2,&c2);
if(c1==r2)
printf("multiplication can be done");
printf("enter the element of 1st matrix");
for(i=0;i<r1;i++)
for(j=0;j<c1;j++)
scanf("%d",&a[i][j]);
printf("enter the element of 2nd matrix");
for(i=0;i<r2;i++)
for(j=0;j<c2;j++)
scanf("%d",&b[i][j]);
for(i=0;i<c1;i++)
for(j=0;j<r2;j++)
{
c[i][j]=0;
for(ir2=0;ir2<c1;ir2++)
c[i][j]=a[i][ir2]*[ir2][j];
}
printf("the multiplication of two matrices is:\n");
for(i=0;i<c1;i++)
for(j=0;j<r2;j++)
printf("%3d",c[i][j]);
printf("\n");
getch();
}
