SUMMARY
In C++, when a variable of type double is assigned an integer value, such as 3, it is stored as 3.0. The C++ language utilizes the declared variable type for value assignment, ensuring that a double retains its decimal representation. Similarly, when a float variable is used, it will also store values as floats, preserving any decimal points in the input. This behavior is consistent across different variable types in C++.
