Assert macro:

  • It denotes a tool to ensure that expected conditions are true at assert statement location.
  • If condition does not meet, then program displays error message and aborts.
  • The assert definition is been included in program with statement “#include<cassert>”.
  • The statement “assert(bool_expr)” is inserted to use “assert”, the “bool_expr” denotes a Boolean expression that should be evaluated to true.
  • The assert statement denotes a macro, that is similar to function.
  • The assert macros can be disabled by adding “#define NDEBUG” before include statement.

Given statement:

x=(x*y/z)

Explanation:

  • The given statement denotes an expression with variables “x”, “y” and “z”.
  • It updates the value of “x”.
  • The value of “z” should not be zero.
  • If the value becomes zero, then it displays division by zero error.
