[英]“Variable” was not declared in this scope
I am getting this error when I try to compile my class. 当我尝试编译我的类时,出现此错误。 I have made sure there is function prototypes and variables are initilized correctly, hopefully someone can help me figure out the problem 我确保有函数原型和变量已正确初始化,希望有人可以帮助我解决问题

Here is my header file 这是我的头文件
#ifndef TRANSACTION_H
#define TRANSACTION_H
#include <string>
using namespace std;
#include "defs.h"
class Transaction
{
public:

int getTransID();

float getAmount();
private:
static int nextTransID;
int transID;
TransType tType;
TransState tState;
string date;

#endif
Here is my source file 这是我的源文件
#include "Transaction.h"
#include "defs.h"
#include <string>
using namespace std;
int Transaction::nextTransID = 2001;
Transaction::Transaction(TransType t, TransState s, int acct, float amount)
{
transID = nextTransID++;
tType = t;
tState = s;
tAcctNum = acct;
tAmount = amount;
}
int getTransID() { return transID; }
TransType getTType() { return tType; }
TransState getTState() { return tState; }

int getTAcctNum() { return tAcctNum; }
float getTAmount() { return tAmount; }
void setDate(string d)
{

}
I am kinda lost on what is the issue 我有点迷失在什么问题上
This: 这个:
int getTransID() { return transID; }
has nothing to do with your class, it's a global function. 与您的课程无关,这是一个全局函数。
You meant: 你的意思是:
int Transaction::getTransID() { return transID; }
Also, that function (and the other getters) should be made const
to signal that they don't modify the object. 同样,应将该函数(和其他获取器)设置为const
以表示它们未修改该对象。
