In this code, we can observe how multiple function calls are connected. Now, let’s take a look at the addTwoInts function. This function simply adds these two integers together and returns the result. Moving on to the main function, this is where the action happens. We have a series ...
[C/CPP系列知识] 在C中使用没有声明的函数时将发生什么 What happens when a function is called before its declaration in C 1在C语言中,如果函数在声明之前被调用,那么编译器假设函数的返回值的类型为INT型, 所以下面的code将无法通过编译:
By default, the MSVC compiler treats all files that end in .c as C source code, and all files that end in .cpp as C++ source code. To force the compiler to treat all files as C no matter the file name extension, use the /TC compiler option. By default, MSVC is compatible with ...
