The only exception to the rule that a value-returning function must return a value via a return statement is for functionmain(). The functionmain()will implicitly return the value0if no return statement is provided. That said, it is best practice to explicitly return a value frommain, both...
Returning a value from a void function is a compile error Trying to return a value from a non-value returning function will result in a compilation error: voidprintHi()// This function is non-value returning{std::cout<<"In printHi()"<<'\n';return5;// compile error: we're trying ...
void表示不返回任何信息，也就是说，用户不应该使用return语句。在void的函数中，使用return;更多的是为了强制性的结束该函数，而不是为了返回一个值。当用户需要在void函数里获得某个信息的时候，可以直接赋值给某个全局变量。
C. I am working on an open source code base written inC. While working on one of its function, I wanted to be sure if I have correctly understood the return value of the following function. Can someone please help me understand what exactly belowfunctionbucket_straw2_chooseis returning?

因为定义的函数f是一个void类型函数，说明此函数调用后，没有返回结果。而在函数体中，有return 语句，想此函数被调用后，返回一个结果。 由此产生了矛盾 另外，变量i没有定义，变量N没有赋初值 printf函数的参数不正确
我在MFC向导生成对话框,添加了三个编辑框,变量分别是m_nNumber1,m_nNumber2,m_nNumber3,然后在在void CTest2Dlg::OnOK()添加了 return m_nNumber3=m_nNumber1+m_nNumber2;想点击OK按钮就在第三个编辑框中输出第三个变量,但是却出现了'void' function returning a value 怎么回事? 查看完整描述...
你在 void main()的结尾加了return 0;不能要
Im trying to connect postgresql db from my server which has ubuntu 18.04 I have the code below but when i compile it I get the error return-statement with a value, in function returning 'void' [-fpermissive] return 1; 1 2 3 4
为什么这个C++程序调试的时候说'main' :'void' function returning a value se 相关知识点: 试题来源: 解析 void类型表示你的main函数无返回值,但是你在main函数体内又加了return 0,也就是说有返回值,这和你前面的void是相冲突的.要么有void,去掉return 0,要么把void 改成 int或者其他数据类型....
