- 1What is an Algorithman algorithm is a sequence of instructions that can be followed to solve a problem
the written code has to be translated into machine code and executed on the computer - 2what is PseudoCodeused to write instructions in statements that are somewhere between English and a programming language
there are no strict guidelines for writing pseudocode - 3Name 5 data typesinteger
string
float/real
Boolean
character - 4Arithmetic OperationsAddition +
Subtraction -
Multiplication *
Division /
Whole number Division //
Modulus %
Power ** - 5Boolean Operators== Equal to
!= Not equal to
> Greater than
< Less than
>= Greater than or equal to
<= Less than or equal to - 6VariableVariables are identifiers given to memory locations whose contents can change during the course of the program.#
usually expressed in lower case letters - 7ConstantA constant cant be changed while the program is running
constants reduce risk of errors by reducing access to the memory location.
constants written in all capital letters with underscores separating words - 8What is the string function to return length of a stringlen(string)
- 9what string function returns a sub string of a stringString.substring(index1, index2)
- 10what string function returns if a string is found within another stringstring.find(substring)
- 11what string function returns the integer equivalent of a characterord(“a”)
- 12What string function returns the character represented by an integer (“a” in this example)chr(97)
