How is a C function prototype turned into a function definition?
ComputerScienceOne / Declaration: Prototypes
"Later in the program, we can provide the actual definition of each function by using the following syntax. We repeat the signature, but instead of using a semicolon, we provide a code block, enclosed using opening/closing curly brackets, that specifies the function body. Here are the definitions from the prototype examples above:\n\nint sum(int a, int b) {\n\nreturn (a + b);\n\n}"
