Example of return value 4 – user type result by valueCopy struct Struct2 { int j, k; // Struct2 fits in 64 bits, and meets requirements for return by value. }; Struct2 func4(int a, double b, int c, float d); // Caller passes a in RCX, b in XMM1, c in R8, and d ...
The specific value returned from a function is called the return value. When the return statement is executed, the function exits immediately, and the return value is copied from the function back to the caller. This process is called return by value. A value-returning function will return a...
pass by value 将实参的值拷贝后赋值给形参,对形参的操作不会影响实参 指针形参 传递指针,拷贝的是指针的值,拷贝后的两个指针是不同的指针,但是由于指针可以间接的访问所指的对象,所以可以通过指针修改它所指的对象值 void reset(int *p){ *p = 0;//改变了指向的对象的值 p = 0;//只改变了p的局部拷贝,...
1.改为空类型，即将main()改成void main()；2.不加void的话主函数默认返回值是int，所以可以把main()改成int main(),再在主函数末尾加入renturn （0）；3.直接只加入return（0）；还有就是这跟编译环境有关，有的环境要求不是很高，就不会报错，可能有警告，但不会影响运行。

这个不是错误，而是一个警告。意思是说001.c这个源文件里的main()函数没有返回值。你这样写就不会出现这个警告了：int main(void){ printf("this is a C program.\");return 0;}

C在傳遞資料進function時,就只有兩招,一招是call by value,一招是call by address(實際上也是一種call by value,只是它copy的是value的address,而不是value本身),一些較小型的型別如int、double,我們會使用call by value配合return,當然使用call by address亦可;而一些較大的型別,如string、array、struct,我們會...
