Class 3/28

Notes

• We discussed using the \ to escape characters
  • This includes \n and \t
  • But also \\
• We then discussed the find and the substring operations with strings.
  • string::npos - a constant bigger than the biggest string.
    • returned from find when the item you are searching for is not present.
    • Used in substr when you want the rest of the string.
  • These ideas are in printSlas.cpp
• We discussed the main loop for rosetta.cpp

   string number;
  string value, label;
  cin >>number;
  // in the form value:label
  // split these into to  value and label
  if (label == "deci") {
        Call DecimalStringToInteger
  } else if (label == "murn") {
        Call UrnfieldStringToInteger
  } else if (label == "maya") {
        Call  MayanStringToInteger
  } else {
        print an error
  }
