Ideas in this flowchart

  • In C, numeric comparison operators cannot be used to compare strings.
  • The expression ("aardvark" < "zebra") is valid C.
  • Although the expression produces a result, that result is not necessarily true or false.
  • The reason is that strings in C are represented as arrays.
  • Arrays are represented as memory locations.
  • These representation issues will be explored in greater depth later.

"Numeric comparison operators cannot be used to compare strings in C. For example, we could write (\"aardvark\" < \"zebra\") which would be valid C, and it would even have a result. However, that result wouldn’t necessarily be true or false . The reason for this is that strings in C are actually represented as arrays, which in turn are represented as memory locations . We’ll explore these issues in greater depth later on, but for now 273"
