C program to find the product of 2 matrices

Write a c program to find the product of 2 matrices.

void main()
{
int a[3][3],b[3][3],c[3][3],i,j,k;
clrscr();
printf("\nEnter the first matrix:\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
scanf("\t%d",&a[i][j]);
printf("\n");
}
printf("\nEnter the second matrix:\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
scanf("\t%d",&b[i][j]);
printf("\n");
}
printf("\nProduct of two matrices\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
c[i][j]=0;
for(k=0;k<3;k++)
{
c[i][j]=c[i][j]+a[i][k]*b[k][j];
}
printf("%d\t",c[i][j]);
}
printf("\n");
}
getch();
}

/*Output
Enter the first matrix:
12 34 45

54 65 67

76 78 89


Enter the second matrix:
87 75 53

90 10 20

30 40 50
