Operators

• CONCEPT: Operators are used to combine expressions (logical operators) or to compare expressions (relational operators)

• Most programming languages have more logical operators than a pocket calculator

  • Operators like + taking 2 operands are called binary: a + b
  • Operators like - taking 1 operand are called unary: - a

• A very useful logical operator is concatenate, & in VB6, which connects two strings together:

  • plural = “dog” & “s”
