Three reference sheets will be available for you during the exam. The C reference card has much more than you need to know about C.
Additionally I am working on a reference sheet covering topics in Chapters 6 and 8.
The second exam covers Chapters 1 to 4, 6, and 8 of the textbook.
The exam will concentrate on topics covered by homework and assignments. There will be also be some "review" problems from Exam 1 and and Exam 2.
Unlike the second exam, this one really will cover pointers. So, let's do this example!
Pointers are in C, but not in Java. A recent CSCI 373 exam asked students to draw the pointers and give the output generated by the following program. If you can do this, you have truly master pointers.
int a, b ;
int *p, *q ;
int v[2] ;
a = 10 ;
b = 20 ;
for (a = 0; a<2; ++a) {
v[a] = 30 + a*10 ;
}
printf("%d %d %d %d\n", a, b, v[0], v[1]) ;
p = &a ;
*p = b + 5 ;
v[0] = *p + 7 ;
printf("%d %d %d %d\n", a, b, v[0], v[1]) ;
p = &a ;
q = &b ;
*p = *q ;
*q = *p ;
printf("%d %d %d %d\n", a, b, v[0], v[1]) ;
q = &v[0] ;
p = q ;
b = *++q ;
a = ++*p ;
printf("%d %d %d %d\n", a, b, v[0], v[1]) ;
p = &v[0] ;
q = &v[1] ;
a = q-p ;
b = *q-*p ;
printf("%d %d %d %d\n", a, b, v[0], v[1]) ;
