Different Character Output

[Ralph]

I wrote a C program as below:
#include <stdio.h>
main()
{
char test[5][10] = {"sample","cow","for","is","well"};
putchar(**(sa+1));
int a=0;
for(a=0; a<5; a++)
{
sa[a] = test[a];
}
putchar(**(sa+1));
}

I thought the above program would give me output as a but it gave me as c. What is the reason for getting c as output? Someone kindly brief me.
