I know strncpy(s1, s2, n) copies n elements of s2 into s1, but that only fills it from the beginning of s1. For example
s1[10] = "Teacher"
s2[20] = "Assisstant"
strncpy(s1, s2, 2) would yield s1[10] = "As", correct?
Now what if I want s1 to contain "TeacherAs"? How would I do that? Is strncpy the appropriate thing to use in this case?
