C ++银行系统项目问题 [英] C++ bank system project problem

问题描述

嘿伙计们我正在开发一个银行系统项目，而且每件事都运作良好

除非我尝试打印我输入的值，我会得到奇怪的字符串和随机数字，这里是代码：

  #include   <   iostream  >  
  使用 命名空间标准; 
 
  struct 地址{
  char  stName [ 10 ]; 
  int  houseNum; 
}; 
 
  struct 帐户{
  char  name [ 10 ]; 
  int  accnumber; 
  double 余额; 
地址地址; 
}; 
  //   -------------------- -------------------------------------------------- --------------------------- //  
  void  getData（帐户account []， int  size， int  * counter）; 
 
 
  //   ------------ -------------------------------------------------- ---------------------------------- //  
  int  main（）{
  int  choice; 
  int  i =  0 ; 
  int  size =  10 ; 
账户a [size]; 
  while （ true ）{
 
 cout<<   \t\t\t ---输入你的选择---< < ENDL; 
 cout<< ENDL; 
 cout<<   \t\t\t 1  - 创建帐户\ n; 
 cout<< ENDL; 
 cout<<   \t\t\t 2  - 存款<< endl; 
 cout<< ENDL; 
 cout<<   \t\t\t 3  - 提取资金<< endl; 
 cout<< ENDL; 
 cout<<   \t\t\t 4  - 显示<< ENDL; 
 cout<< ENDL; 
 cout<<   \t\t\t 5  - 退出<< ENDL; 
 cout<< ENDL; 
 cout<<   \t\t\t选项是：; 
 cin>>选择; 
  if （choice ==  1 ）
 getData（a，size，& ;一世）; 
 
  //   printnig value  - >只需检查 
 cout<< endl<< ENDL; 
 cout<<  名称：<< a [i] .name<< ENDL; 
 cout<<  帐号：<< a [i] .accnumber<< ENDL; 
 cout<<  余额：<< a [i] .balance<< ENDL; 
 cout<<   House num：<< a [i] .addr.houseNum<<结束
 cout<<  街道名称：<< a [i] .addr.stName<< ENDL; 
 
} 
 
} 
 
  void  getData（账户账户[]， int  size， int  * counter）{
  int  i = * counter; 
 
 cout<<  名称：; 
 cin>>帐户[I]。名称; 
 
 cout<<   acc number：; 
 cin>>帐户[I] .accnumber; 
 cout<<   balance：; 
 cin>>帐户[I] .balance; 
 cout<<  地址信息<< ENDL; 
 cout<<  门牌号：; 
 cin>>帐户[I] .addr.houseNum; 
 cout<<  街道名称：; 
 cin>> accounts [i] .addr.stName; 
 i ++; 
 * counter = i; 
 cout<< ENDL; 
 cout<<  完成....<< ENDL; 
 system（  pause）; 
} 

我的尝试：



i没有任何线索，是什么导致它表现得那样!!

解决方案

你的问题是 i ++ ...您将值存储在 i 的位置，但会增加它并在位置 i ++ ...

hey guys i'm working on a bank system project and every thing is working well
except when i try to print the values i entered i get wierd strings and random numbers ,, here's the code :

#include <iostream>
using namespace std;

struct Address{
	char stName[10];
	int houseNum;
};

struct Account{
	char name[10];
	int accnumber;
	double balance;
	Address addr;
};
// ------------------------------------------------------------------------------------------------- //
void getData( Account accounts[], int size , int *counter);


// ------------------------------------------------------------------------------------------------ //
int main(){
int choice;
int i = 0;
int size = 10;
Account a[size];
while (true){

	cout << "\t\t\t --- Enter your choise --- " << endl;
	cout << endl;
	cout << "\t\t\t 1 - Create Account\n";
	cout << endl;
	cout <<"\t\t\t 2 - Deposit Money" <<endl;
	cout << endl;
	cout << "\t\t\t 3 - Withdraw Money" <<endl;
	cout << endl;
	cout << "\t\t\t 4 - Display" << endl;
	cout << endl;
	cout << "\t\t\t 5 - Exit" << endl;
	cout << endl;
	cout << "\t\t\t choice is :  ";
	cin >> choice;
	if (choice == 1)
	getData(a , size ,&i);
	
	// printnig the value -> just checking
	cout << endl << endl;
	cout << "Name: " << a[i].name << endl;
	cout << "Account number : " << a[i].accnumber << endl;
	cout << "Balance: " << a[i].balance << endl;
	cout << "House num: " << a[i].addr.houseNum << endl ;
	cout << "Street name: " << a[i].addr.stName << endl;
	
}
	
}

void getData(Account accounts[], int size,int *counter ){
	int i = *counter;
	
	cout << "Name: ";
	cin >> accounts[i].name;
	
	cout << "acc number : " ;
	cin >> accounts[i].accnumber;
	cout << "balance : " ;
	cin >> accounts[i].balance;
	cout << "Address info " << endl;
	cout << "House number : " ;
	cin >> accounts[i].addr.houseNum;
	cout << "Street name : ";
	cin >> accounts[i].addr.stName ;
	i++;
	*counter = i;
	cout << endl;
	cout << "Done ...." << endl;
	system("pause");
}

What I have tried:

i have no clue ,, what is causing it to behave like that !!

解决方案

Your problem is i++... You are storing the values at position i, but increments it and prints the values at position i++...
