Min float: -3.40282e+38
Code Explanation:
The program begins by including necessary header files for input-output operations, vectors, maps, bitsets, and to access numerical limits of data types.
Then we declare and initialize several primitive data types: an integer, a float, a double, a character, and a boolean. These basic types are fundamental to C++ and are used to represent simple data.
The standard output, std::cout
, is used to print the values of these variables to the console, illustrating how to format a boolean with std::boolalpha
.
Next, the program demonstrates advanced types in C++. It initializes a vector of integers, a map with string keys and integer values, and an 8-bit bitset. These advanced structures allow for more complex data storage and manipulation.
The program then iterates over the vector and map, printing their contents. The bitset is printed directly, showing its binary representation.
Finally, the program prints the maximum and minimum values that can be represented by an int and float using std::numeric_limits
. This demonstrates how to retrieve the range of values supported by various data types.
The program’s logic is simple: declare variables of different data types, initialize them, and print their values to showcase both basic and advanced types in C++. The architecture of the program is straightforward, focusing on the concept of data types within C++ and how they are used.
