Write a program to multiply the two given 2 x 2 matrixes


//program to multiply two matrix and print its result
void main()
{
int a[2][2],b[2][2],c[2][2],i,j,k;
clrscr();
printf("\nEnter the elements for matrix A ");
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
scanf("%d",&a[i][j]);
}}
printf("\nEnter the elements for matrix B ");
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
scanf("%d",&b[i][j]);
}}
printf("\nThe multiplication result of the above matrices is given below\n");
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
c[i][j]=0;
for(k=0;k<2;k++)
{
 c[i][j]=c[i][j]+a[i][k]*b[k][j];
   }
  }
 }
 for(i=0;i<m;i++)
{
for(j=0;j<p;j++)
{
printf("%d ",c[i][j]);
}
printf("\n");
}
getch();
}
Output
Enter the elements for matrix A
1 2
3 4
Enter the elements for matrix B
5 4
6 7

The multiplication result of the above matrices is given below
17 18
39 40
