Print Cheatsheet

Mathmatical Symbols in C

C is able to perform basic mathematical operations on variables and values using the following symbols:

  • Addition: +
  • Subtraction: -
  • Division: /
  • Multiplication: *
  • Incrementing: ++
  • Decrementing: --
  • Modulo: %

Assignment Operations in C

C can assign values to variables and perform basic mathematical operations using shorthand operators:

  • Assignment: =
  • Addition then assignment: +=
  • Subtraction then assignment: -=
  • Multiplication then assignment: *=
  • Division then assignment: /=
  • Modulo then assignment: %=

Comparing values in C

C can compare two values and/or variables against each other to return true or false. The operators are as follows:

  • Do both sides have the same value? ==
  • Do the two sides have different values? !=
  • Is the left side a lower value than the right side? <
  • Is the left side a lower or equal value to the right side? <=
  • Is the left side a greater value than the right side? >
  • Is the left side a greater or equal value to the right side? >=

Logical Operators in C

C can perform logical operations using the following operators:

  • and: && (Are both sides true?)
  • or: || (Is at least one side true?)
  • not: ! (True becomes false and false becomes true.)
