type functionName( type [argname] [, type, ...] ); Example: // declare a function prototype for the add function, taking two integer // arguments and returning their sum int add (int lhs, int rhs); In C and C+
Explanation:In this example, a function named print_value is defined to take a const reference to an integer as its argument. Since the argument is declared as const, cannot modify within the function. The function simply prints the value of the argument to the console. In the main, an in...
On 68HC11 the compiler will generate a sequence of instructions to invoke a board-specific routine to switch the memory bank and call the real function. The board-specific routine simulates acall. At the end of a function, it will jump to a board-specific routine instead of usingrts. The...
If you want to use a function across multiple source files, you should declare the function in one header file (.h) and then put the function definition in one source file (.c or .cpp). All code that uses the function should include just the .h file, and you should link the resulti...
