CS201: Elementary Data Structures

Upon successful completion of this unit, you will be able to:

• Interpret native C/C++ variable declarations relative to data organization and access.
  • Illustrate the difference between scalars, vectors, and arrays.
  • Describe the various types of scalars.
  • Show how scalars, vectors, and arrays are used to organize values according to a specific multi-dimensional categorization.
  • Demonstrate how the range of a numeric scalar type can be extended via compound declarations.
  • Explain why scalar types may not have the same numeric range from one compiler to another on the same machine.
  • Explain why scalar types may not have the same numeric range using the same source-code on different machines of the same word size.
  • Choose access approaches appropriate to contiguous and non-contiguous memory cases
• Choose approaches to using pointer variables for memory access within scalars, vectors, and arrays.
  • Define pointer variable.
  • Relate the value of a pointer variable to the location of a variable's value in memory.
  • Explain how to declare a pointer variable in C/C++.
  • Explain how to get the memory location of a scalar value.
  • Show how pointer math is used to access specific elements of a vector or array existing in contiguous memory.
