invalid operands to binary expression 错误解答 1. 错误含义 "invalid operands to binary expression" 错误表明在尝试执行二元运算(如加法、减法、比较等)时,操作数的类型不兼容或不支持该操作。在C++等编程语言中,这种错误通常会在编译时发生,因为编译器无法找到适合这两个操作数的运算符重载或隐式类型转换。 2....

这段代码我在编译时 ,提示 error: invalid operands to binary expression 请问是我哪里做错了吗?
报错Error: fs_server.cpp:264:56: error: invalid operands to binary expression ('__bind<int &, sockaddr *, unsigned long>' and 'int') if (bind(sockfd, (sockaddr *) &addr, sizeof(addr)) == -1) { 1. 2. 3. 问题描述: This was working when I run this code using C++11, and ...
在C语言编译时,若出现"invalid operands to binary"错误,表示二进制运算符未被正确使用。这个问题常见于操作符两边的运算对象类型不一致。例如,使用百分号(%)运算符时,两边必须为整型,若使用其他类型将导致错误。为解决此类问题,首先要检查涉及到二进制运算符的代码段。确认两边操作数的类型是否符合...
开根号,不能这样写 :(1.0-x*sin(t)*sin(t))^0.5)要写成:sqrt( 1.0-x*sin(t)*sin(t) )^是C中的“异或”运算符,不是开方运算符!
