can somebody help me understand how char * work?

char * s1;
s1 = "assign a value";
s1 = "assign another value"; //does c auto deallocate storage and
reallocate a longer one for this assignment?

. . .



char * s1
int myInt = 10;

sprintf(s1, "test %i", myInt); //why is s1 contains *null after this
assignment?
