multiplication of two numbers say 2*3 is similar to adding
the first number the second number of times(i.e in our
example 2+2+2 will give 2*3)
hence,


int add(int m,int n)
{
static int res;
if(n==1)
return m;
else
res=m+add(m,n);
printf("%d\n",res);
return ;
}

int main()
{
int m,n;
printf("enter the two numbers\n");
scanf("%d%d",&m,&n);
add(m,n);
return 0;
}
