Document Summary
C++ allows more than one definition for the same function name: co(cid:374)(cid:448)e(cid:374)ie(cid:374)t for situatio(cid:374)s i(cid:374) (cid:449)hi(cid:272)h the (cid:862)sa(cid:373)e(cid:863) fu(cid:374)(cid:272)tio(cid:374) is (cid:374)eeded for different numbers of types of arguments. Overloading function name: providing more than one declaration and definition using the same function name. Compiler checks the number and types of arguments in the function call decides which function to use. Overloaded functions must: have different numbers or formal parameters, and/or. Have at least one different type of parameter. Return a value of the same type. C++ will automatically convert types between int and double in multiple examples ie. diving integer by double results in double. C++ does the same with overloaded functions. The compiler chooses the function that matches parameter types. *do not use the same function name for unrelated purposes! void functions. In a top-down design, (cid:449)e"ll (cid:449)a(cid:374)t to desig(cid:374) su(cid:271)tasks, ofte(cid:374) i(cid:373)ple(cid:373)e(cid:374)ted as fu(cid:374)(cid:272)tio(cid:374)s.
