Program Plan Intro

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.
