The function prototype is not needed if the user-defined function is defined before themain()function. Calling a function Control of the program is transferred to the user-defined function by calling it. Syntax of function call functionName(argument1, argument2, ...); In the above example, ...
How user-defined function works? #include <stdio.h> void functionName() { ... .. ... ... .. ... } int main() { ... .. ... ... .. ... functionName(); ... .. ... ... .. ... } The execution of a C program begins from the main() function. When the compile...
In the main() function of our program, we often need to use some user defined functions to do our calculating work. For a user_function, we may transfer into several int variable, and return a variable. or, we may need modify a data array by calling a function. And return void. or,...

When multiple files compile against a single function, the declaration for that function must be in a single header file. This allows maintainers to update the function declaration in a single place and detect any errors at compile time. This also makes it impossible to declare the function usi...
1、Compound statement missing } in function main 程序结尾缺少括号}。 2、“}”expected; “(”expected等 复合语句或数组初始化的结尾缺少“)”;“(”。 3、 Case outside of switch case 不属于Switch结构,多由于switch结构中的花括号不配对所致。
