Here we will see what are the differences between structures in C and structures in C++. The C++ structures are mostly like classes in C++. In C structure, all members are public, but in C++, they are private in default. Some other differences are listed below.
| C Structure | C++ Structure |
|---|---|
| Structures in C, cannot have member functions inside structures. | Structures in C++ can hold member functions with member variables. |
| We cannot initialize the structure data directly in C. | We can directly initialize structure data in C++. |
| In C, we have to write ‘struct’ keyword to declare structure type variables. | In C++, we do not need to use ‘struct’ keyword for declaring variables. |
| C structures cannot have static members. | C++ structures can have static members. |
| The sizeof operator will generate 0 for empty structure in C | The sizeof operator will generate 1 for empty structure in C++ |
| The data hiding feature is not available in C structures. | The data hiding feature is present in C++ structures. |
| C structures does not have access modifiers. | C++ structures have access specifiers. |
