Here we will see how to map some enum type data to a string in C++. There is no such direct function to do so. But we can create our own function to convert enum to string . We shall create a function that takes an enum value as the argument, and we manually return the enum names as a string from that function.
Read moreCan you switch on an enum C++?
In C++, enums are permitted to have values other than the explicit enumerators. … After execution falls through the switch statement, it reaches the end of the function without returning a value, which is undefined behavior for a function with a non-void return type.
Read moreWhat is union and enum in C++?
That is the main difference between structure union and enum in C. … Structure and union are two methods to store multiple variables of different types as a single variable . On the other hand, enum is a data type to declare a set of named constants. All these are user-defined data types.
Read moreWhat is union explain with example?
A union is a user-defined type similar to structs in C except for one key difference . Structures allocate enough space to store all their members, whereas unions can only hold one member value at a time.
Read moreWhat are the uses of union?
The primary use of a union is allowing access to a common location by different data types , for example hardware input/output access, bitfield and word sharing, or type punning. Unions can also provide low-level polymorphism.
Read moreWhat is the difference between union and struct in C++?
A union is like a struct in that it generally has several fields , all of which are public by default. Unlike a struct, however, only one of the fields is used at any given time. In other words, it is a structure that allows the same storage space to be used to store values of different data types at different times.
