‘validKPs’ was not declared in this scope

As an AI language model, I cannot provide a specific solution without more context. However, the error message suggests that the variable 'validKPs' has not been declared in the current scope. This could mean that it has not been defined or initialized, or that it is out of the current scope where it is being used.

To resolve this error, you may need to check the scope of the variable and ensure that it is properly declared and initialized before being used in the current scope. You may also need to check for any typos or syntax errors in the code.

was not declared in this scope

"was not declared in this scope"是C++中常见的一个编译错误提示，意为“该标识符在当前作用域中未声明”。

在C++中，作用域是指程序中变量、函数、类等定义所适用的特定区域。如果在当前作用域中使用了一个未声明的标识符（比如一个未定义的变量或函数名），则编译器会报错。

例如，如果在一个函数中使用了一个未声明的变量，编译器会输出类似于“‘variable’ was not declared in this scope”的错误信息。同样地，如果在一个类的成员函数中使用了未声明的类成员变量或函数，则编译器也会报错。

解决这个错误的方法是在当前作用域内为该标识符声明并定义相应的变量、函数、类等。如果需要在其他作用域中使用该标识符，可以通过引入头文件等方法在其他作用域中声明该标识符。

总之，C++编译错误“was not declared in this scope”意味着程序中出现了未声明的标识符，需要在相应的作用域中确认并定义该标识符，才能成功编译运行程序。

'TSnedCycle' was not declared in this scope

在代码中出现'TSnedCycle' was not declared in this scope的错误，意味着该变量或函数未在当前作用域中声明。这可能是由于变量或函数名称的拼写错误，或者是因为它们未被正确地声明或定义所致。要解决此问题，您可以尝试在代码中查找变量或函数的正确拼写，并确保它们已在当前作用域中正确声明或定义。

举个例子：

#include <iostream>
using namespace std;

int main() {
   TSnedCycle(); // 'TSnedCycle' was not declared in this scope
   return 0;
}

void TSnedCycle() {
   cout << "Hello World!";
}

在上面的代码中，当我们尝试调用函数TSnedCycle()时，会出现'TSnedCycle' was not declared in this scope的错误。要解决此问题，我们需要在main函数之前声明或定义TSnedCycle函数，如下所示：

#include <iostream>
using namespace std;

void TSnedCycle(); // 声明函数

int main() {
   TSnedCycle(); // 调用函数
   return 0;
}

void TSnedCycle() {
   cout << "Hello World!";
}
