Pointers & Arrays, Stack & Heap memory. Learning & Development Team. http://academy.telerik.com. . Telerik Software Academy. CSE 2451. Rong. Shi. Language comparison. C has pointers. Java has references. C++ has pointers . and . references. Pointers. Values of variables are stored in memory, at a particular location. A location is identified and referenced with an address. Suppose you need to write a program that stores the student ID numbers of 20 students and then the grades for each of them on three different tests. You could create 4 parallel arrays to hold this data; but, it would be nice to put the test grades all into one storage structure. Something like the table below:. CSE 2451. Rong. Shi. Arrays. Store many values of the same type in adjacent memory locations. Declaration <type> <name> [<size>] . Examples:. int. . rgb. [3];. double . percents. CSSE 332. Operating Systems.
