c function return
一個很簡單的需求，傳入兩個整數後，希望同時傳回相加與相乘的結果。 C語言. 1 /* 2 (C) OOMusou 2008 http://oomusou.cnblogs.com 3 4 Filename : fuction_return_two_value.c 5 Compiler : Visual C++ 8.0 6 Description : Demo how to return 2 value by C 7 Release : 03/15/2008 1.0 8 */ 9 10 #include &,int (*getFunc())(int, int) … } That provides the declaration you requested. Additionally, as ola1olsson notes, it would be good to insert void : int (*getFunc(void))(int, int) … } This says that getFunc may not take any parameters, which can help avoid ,These function may or may not return values to the calling functions. All C functions can be called either with arguments or without arguments in a C program. Also, they may or may not return any values. There are following categories: Function with no ar,How you divide up your code among different functions is up to you, but logically the division is such that each function performs a specific task. A function declaration tells the compiler about a function's name, return type, and parameters. A funct,Unlike some languages such as Groovy where the last expression evaluated by a function is the return value of the function, in C you need to explicitly state the return value with a return statement. int checkIfPrime(int n) int flag = 1; for (int i = 2; ,int f(char) return 0; } int (*return_f())(char) return f; }. No, seriously, use a typedef :). ,C programming does not allow to return an entire array as an argument to a function. However, you can return a pointer to an array by specifying the array's name without an index. If you want to return a single-dimension array from a function, you wou,Return pointer from functions in C - Learn C programming in simple and easy steps starting from basic to advanced concepts with examples including C Overview, language basics, Environment Setup, Program Structure, Basic Syntax, literals, data types, Varia,jump-statement: return expression opt;. The value of expression, if present, is returned to the calling function. If expression is omitted, the return value of the function is undefined. The expression, if present, is evaluated and then converted to the t,C語言使用的函數可以寫出非常漂亮的程式結構，使程式簡單化，偵錯容易。 2. 將重複之某 ...
