这个xx指的是一半都是运算符,比如++,—等 错误的原因是:把类型(type)当成变量来用了(variable) 一般来说,常见的int,double这种基本的类型是不会错的,因为有语法高亮很明显,但是如果是自己定义的类型,就较有可能出错了 #include<bits/stdc++.h> using namespace std; typedef long long LL; int main() { ...

“expected primary-expression before”出现"int"是什么意思? 是代码有语法错误,好好检查一下,比如看看是不是多了大括号。概述目前在一般的电脑中,int占用4字节,32比特,数据范围为-2147483648~2147483647[-2^31~2^31-1]在之前的微型机中,int占用2字节,16比特,数据
but they still exist. I used one near the bottom of my code. I keeping getting the error: expected primary-expression before 'float' and im not sure what I am doing wrong. I probably didn't code this in the best manner but oh well. what can I say im a noob.:) help would be ...
