错误C2061：语法错误：标识符'finalScore' [英] error C2061: syntax error : identifier 'finalScore'

问题描述

我的代码遇到了问题。这是我的第一个C ++项目。我一直在我的标识符上得到错误，但它在代码的早期工作正常。有小费吗？谢谢你好

Hi, I am having trouble with my code. This is my first C++ project. I keep getting the error on my identifier, but it works fine earlier in the code. Any tips? Thank yo

#include <iostream>
using namespace std;


int main()
{
		int finalScore;
		cout << "Please enter your final test score  > ";
		cin >> finalScore;

		{if (finalScore >= 60)
			cout << "Congratulations you have passed";

		else if (finalScore < 60)
			cout << "You have failed.Next time try harder."; }

		system("PAUSE");
	return 0;

}

推荐答案

如果你写的是

If you write

#include <iostream>

不会有任何编译错误。如果您有一些错误，则无法与此标识符相关联。检查 #include 行中的内容。我只是解释：你的观察是不正确的。干净地重建项目。



解决方案1错误，但建议是正确的：您不需要这些额外的括号。

另外，如果（finalScore< 60），用 else 替换 else。我甚至要解释原因吗？另外，避免立即常量如60，而是声明显式常量，否则你的代码将不适合维护。

there won't be any compilation errors. If you have some errors, they cannot be related with this identifier. Check up what's in the #include line. I have only on explanation: your observation is incorrect. Rebuild the project cleanly.

Solution 1 is wrong, but the advice is correct: you don't need these extra brackets.
Also, replace else if (finalScore < 60) with else. Do I even have to explain why? Also, avoid immediate constants like 60, instead, declare explicit constant, otherwise your code would be bad for maintenance.

我尝试删除花括号，但它不会改变任何东西。似乎它没有读取变量finalScore，但我不确定为什么。我已经按照我的书中的格式示例，尝试使用Google搜索，但仍然丢失了。任何帮助将不胜感激。

I tried removing the curly braces, but it does not change anything. It seems like it is not reading the variable finalScore, but I am not sure why. I have followed the format example from my book, and have tried googling this, but am still lost. Any help would be appreciated.
