After this module, students will be able to:

• Predict the results of running C code that uses pointers and arrays.
• Describe the programmer’s view of memory and explain how this relates to segmentation faults, bus errors, and memory leaks.
• Implement a C program that uses pointers, arrays, and dynamic memory to solve a well- specified problem described in English.
