我是c ++的新手,我想要包含一个Enum值数组,我在Microsoft Visual Studio中遇到语法错误。我不确定为什么会出现这种情况。错误号是C2061,它表示“语法错误:标识符'VerboseBinary'。这是代码:
头文件verbose_binary.h
#pragma once
#include <bitset>
enum class VerboseBinary : int {
One,
Two,
Four,
Eight,
Sixteen,
Null,
};
void convert(std::bitset<5> bs, VerboseBinary aVB[6]);
verbose_binary.cpp
#include "verbose_binary.h"
#include "stdafx.h"
#include <bitset>
#include <string>
#include <iostream>
void convert(std::bitset<5> bs, VerboseBinary aVB[6]) {
VerboseBinary VBArray[6] = {
VerboseBinary:: One,
VerboseBinary:: Two,
VerboseBinary:: Four,
VerboseBinary:: Eight,
VerboseBinary:: Sixteen,
VerboseBinary:: Null
};
for (int i = 0; i < 5; i++) {
if (bs.test(i)) {
aVB[i] = VBArray[i];
}
else {
aVB[i] = VerboseBinary::Null;
}
}
aVB[5] = VerboseBinary::Null;
}
主要
#include "stdafx.h"
#include <iostream>
#include <iostream>
#include <bitset>
#include "verbose_binary.h"
int main() {
int a, b;
std::bitset<5> aBs, bBs;
std::cout << "Enter two numbers between 0-31:" << std::endl;
std::cin >> a >> b;
if (a<0 || a>31) return -1;
if (b<0 || b>31) return -2;
aBs = static_cast<std::bitset<5>>(a);
bBs = static_cast<std::bitset<5>>(b);
// std::cout << aBs << " " << bBs << std::endl;
VerboseBinary aVB[6];
VerboseBinary bVB[6];
convert(aBs, aVB);
convert(bBs, bVB);
return 0;
}
答案 0 :(得分:1)
大声笑,所以看起来其中一个问题是错误的:
您使用的是哪个版本的Visual Studio?随着VS 2012的上课,enum with class。
此外,在枚举结尾处有一个逗号逗号。
此外,stdafx.h应该出现在verbose_binary.cpp中的任何其他包含之前。
Main为<iostream>
