Initializing structure structure_name variable_name = {value1,value2,…,valueN}; Initializing nested structure structure_name variable_name = { {value1, value2},{value3,value4}}; A structure can be nested up to any depth in theory. Structure can hold data and functions (In c they can only hold data) An enum declaration defines the set of all names that will be permissible values of the […]

Before C++ true and false were represented as 1 and 0 respectively. But C++ uses both. Other than 0 all values represent true. Library function exit() : exit(0) : Normal Exit exit(other numerical value) : Error / Abnormal exit. This function is present in ‘process.h’ Library function getche(): This function is present in conio.h No […]
