program.<\/p>\n<p>A function is a block of code that can be called repeatedly. It is defined by a function declaration and a function definition. The function declaration specifies the name of the function, the type of its parameters, and the type of its return value. The function definition contains the code that is executed when the function is called.<\/p>\n<p>In C++, a function can only be defined once in a program. If you try to define the same function more than once, you will get an error. This is because C++ uses a name lookup algorithm to resolve function calls. The name lookup algorithm looks for the definition of a function in the current scope. If the function is not defined in the current scope, it looks in the enclosing scopes. If the function is not defined in any scope, the compiler will generate an error.<\/p>\n<p>There are a few exceptions to this rule. For example, you can define a function in a header file and then include that header file in multiple source files. This is because the name lookup algorithm will only look for the definition of a function in the current scope and in the enclosing scopes. It will not look in the header files that are included in the source file.<\/p>\n<p>Another exception is that you can define a function in a namespace and then use that namespace in multiple source files. This is because the name lookup algorithm will look for the definition of a function in the current scope, in the enclosing scopes, and in the namespaces that are declared in the current scope.<\/p>\n<p>Overall, C++ does not allow you to define the same function more than once in the same program. There are a few exceptions to this rule, but they are limited.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[683],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>C++ allows you to define the same functions more than once in the same program _____ A. if the definitions are identical B. if the definitions are included in two separate #include files C. if the definitions are located in a single #include file that is included more than once D.
