The Multiple Definitions of C++

C++ is a popular programming language used for developing computer software and applications. It is an extension of the C language and provides additional features such as object-oriented programming. However, when working with C++, one may encounter the issue of multiple definitions.

What are Multiple Definitions in C++?

Multiple definitions occur when a program has more than one definition for a single entity such as a function or a variable. This can happen when different source files include the same header file which contains the definition of the entity. When the program is compiled, the linker will try to link the different definitions together and will generate an error if it finds multiple definitions.

How to Avoid Multiple Definitions?

There are several ways to avoid multiple definitions in C++. One way is to use header guards in header files to prevent multiple inclusion. Header guards are preprocessor directives that ensure that header files are included only once in a program. They are defined using the #ifndef and #define directives.

Another way to avoid multiple definitions is to use the extern keyword before the declaration of a variable or function in a header file. This tells the compiler that the entity is defined in another source file and should not be included in the current file. The actual definition of the entity can then be provided in a separate source file.

Table of Common Keywords in C++

Keyword Meaning
int integer data type
double floating-point data type
bool Boolean data type
char character data type
if conditional statement
for looping statement
class user-defined data type
namespace encapsulation of identifiers

Conclusion

In conclusion, multiple definitions can be a common issue when working with C++. However, it can be avoided by using header guards or the extern keyword. It is also important to be familiar with common keywords in C++ such as int, double, bool, and char.
