c语言模拟银行_编写一个C语言程序模拟银行ATM机的账户管理功能系统主要实现以下功能

⑴ 用c语言模拟银行账号密码登录，那个大神可以指导一下

#include<stdio.h>
#include<conio.h>
#include<string.h>
#include<stdlib.h>

intchcode(){
	charpw[50],ch;
	char*syspw="abc";//原始密码
	inti,m=0;
	printf("请输入密码:");
	while(m<3){
		i=0;
		while((ch=_getch())!='
'){
			if(ch==''&&i>0){
				printf("");
				--i;
			}
			elseif(ch!=''){
				pw[i++]=ch;
				printf("*");
			}
		}
		pw[i]='';
		printf("
");
		if(strcmp(pw,syspw)!=0){
			printf("密码错误，请重新输入!
");
			m++;
		}
		else{
			printf("密码正确！
");
			system("pause");
			return1;
		}
	}
	printf("连续3次输入错误，退出!
");
	system("pause");
	return0;
}

intmain(){
	intlogin=chcode();
	if(login)printf("登录成功!
");
	elseprintf("登录失败!
");
	return0;
}

⑵ 编写一个c语言程序，模拟银行帐户交易管理系统。写好给20块钱的分或者q币

http://..com/link?url=koYWtHTk-_IhrTRC90-
这地方有的啊

⑶ C语言用队列结构模拟,银行业务排队系统实现 1.有储户要办理存取款业务时,取号等待,编号入队

很明显这个只要实现队列一切就简单了其实c++有quene类这里我们自己实现它

剩下的自己来写就好了很简单的

首先一个链表的

#include<iostream>
usingnamespacestd;
//链表
typedefstructQDode
{
intn;
	structQDode*next;
}*pqdode,qdode;
//队列
typedefstructMyQueue
{
	pqdodefront;
	pqdoderear;
}*pmyqueue,myqueue;
boolInit_queue(pmyqueuequ);//初始化队列
boolIs_empty(pmyqueuequ);//判断队列是否为空
voidPut_queue(pmyqueuequ,intval);//入队
intOut_queue(pmyqueuequ);//出队
intTravel_queue(pmyqueuequ);//遍历队列
voidDestory_queue(pmyqueuequ);//销毁队列
//主函数
intmain()
{
myqueuequeue={NULL,NULL};

Init_queue(&queue);//初始化

	Put_queue(&queue,5);//入队

	if(!Is_empty(&queue))
	{
		cout<<"队列不为空"<<endl;
	}

	Put_queue(&queue,6);
Put_queue(&queue,7);
	Put_queue(&queue,8);
	Put_queue(&queue,9);


Travel_queue(&queue);//遍历

	intval=Out_queue(&queue);
	cout<<endl<<endl<<val<<endl<<endl;

	Travel_queue(&queue);//遍历
	
	intvall=Out_queue(&queue);
	cout<<endl<<endl<<vall<<endl<<endl;

Travel_queue(&queue);//遍历

	Destory_queue(&queue);//销毁
cout<<endl;
	return0;
}
boolInit_queue(pmyqueuequ)
{
	qu->front=newqdode;
	if(qu->front==NULL)
	{
		cout<<"动态分配内存失败!"<<endl;
		returnfalse;
	}
	else
	{
qu->rear=qu->front;
		qu->front->next=NULL;
		returntrue;
	}
}
voidDestory_queue(pmyqueuequ)
{
	pqdodep=qu->front,q=NULL;
	while(p)
	{
q=p->next;
deletep;
		p=q;
	}
	p=NULL;
}
voidPut_queue(pmyqueuequ,intval)
{
	qu->rear->n=val;
	pqdodeq=qu->rear;
	pqdodep=newqdode;
	p->next=NULL;
	qu->rear=p;
q->next=p;
}
boolIs_empty(pmyqueuequ)
{
	if(qu->front!=qu->rear)
	{
		returnfalse;
	}
	else
	{
		returntrue;
	}
}
intTravel_queue(pmyqueuequ)
{
intcount=0;
	if(Is_empty(qu))
	{
		cout<<"该队列为空！"<<endl;
		return0;
	}
	else
	{
pqdodep=qu->front,q=NULL;
		while(p!=qu->rear)
		{
			count++;
			cout<<p->n<<"";
			if(!(count%5))
			{
				cout<<endl;
			}
			p=p->next;
		}
returncount;
	}
	
}
intOut_queue(pmyqueuequ)
{
	if(Is_empty(qu))
	{
		cout<<"该队列为空！"<<endl;
		return-1;
	}
	else
	{
intval=qu->front->n;
		pqdodep=qu->front->next;
		deletequ->front;
		qu->front=p;
	returnval;
	}
}

然后一个数组实现的

#include<iostream>

usingnamespacestd;

classQUEUE//队列类
{
private://私有成员
	int*pBase;
	intfront,rear;
	intcount;
public://公有成员
boolIs_empty();//判断是否为空
	boolIs_full();//判断是否满
voidenter_queue(intn);//入队
intout_queue();//出队
	voidtravel_queue();//遍历队
	QUEUE(intnumber=100)
	{
front=rear=0;
pBase=newint[number+1];
		count=number+1;
	}
~QUEUE()
	{
		delete[]pBase;
	}
};
intmain()
{
QUEUEqueue(5);
	queue.enter_queue(1);
	queue.enter_queue(2);
	queue.enter_queue(3);
	queue.enter_queue(4);
	queue.enter_queue(5);
queue.enter_queue(6);
	queue.travel_queue();
	queue.out_queue();
	queue.travel_queue();
	queue.out_queue();
	queue.travel_queue();
	queue.out_queue();
	queue.travel_queue();
	queue.out_queue();
	queue.travel_queue();
	queue.out_queue();
	queue.travel_queue();
	queue.out_queue();
	if(queue.Is_full())
	{
		cout<<"wangbadan"<<endl;
	}
	intn=queue.out_queue();
	cout<<n<<endl;
	queue.travel_queue();
	intn1=queue.out_queue();
	cout<<n1<<endl;
	queue.travel_queue();
	return0;
}
boolQUEUE::Is_empty()//判断是否满
{
if(front==rear)
{
		returntrue;
}
	else
	{
		returnfalse;
	}
}
boolQUEUE::Is_full()//判断是否空
{
	if((rear+1)%count==front)
	{
		returntrue;
	}
	else
	{
		returnfalse;
	}
}
voidQUEUE::enter_queue(intn)//入队
{
	if(Is_full())
	{
		cout<<"队列已满！"<<endl;
	}
	else
	{
		pBase[rear]=n;
	rear=(rear+1)%count;
	}
	return;
}
intQUEUE::out_queue()//出队
{
	intn=pBase[front];
if(Is_empty())
{
		cout<<"该队列已空！"<<endl;
		returnfalse;
}
	else
	{
		front=(front+1)%count;
		returnn;
	}
}
voidQUEUE::travel_queue()//遍历
{
	intj=0;
	for(inti=front;i%count!=rear;i++)
	{
		j++;
		cout<<pBase[i%count]<<"";
		if(j==5)
		{
cout<<endl;
			j=0;
		}
	}
	if(j)
	{
		cout<<endl;
	}
	return;
}

⑷ 编写一个C语言程序模拟银行ATM机的账户管理功能，系统主要实现以下功能

按照你的愿意把空都填好了，VC++ 6.0下编译能通过，有警告信息，运行基本上能用，不过个人认为这个系统有很大的不足，比如输入账号的时候没有输出反馈信息，以及没有对误操作的处理等等。需要的话可以帮你改改！

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <string.h>
#define AN 9 //表示账号8位
#define PN 7 //表示密码6位
#define ASN 3 //表示系统中共有3个账户信息
struct Account
{
char accountnumber[AN]; //表示账号信息
char password[PN]; //表示账户的密码信息
double balance; //表示账户的余额
};
struct Account ats[ASN]={{"00000001","123456",100},{"00000002","123456",200},{"00000003","123456",300}};
//ats数组用于存储系统中三个账户的信息
int isCorrect(char *an,char *psd)
{
int i;
for(i=0;i<ASN;i++)
if(strcmp(ats[i].accountnumber,an)==0 && strcmp(psd,ats[i].password)==0)
return 1;
return 0;
}
double getBalance(char *an)
{
int i;
for(i=0;i<ASN;i++)
if(strcmp(an,ats[i].accountnumber)==0)
return ats[i].balance;
}

void deposit(char *an,int amount)
{
int i;
for(i=0;i<ASN;i++)
if(strcmp(an,ats[i].accountnumber)==0)
ats[i].balance+=amount;
}
int withdraw(char *an,int amount)
{
int i;
for(i=0;i<ASN;i++)
if(strcmp(an,ats[i].accountnumber)==0)
return ats[i].balance-=amount;
}

void main()
{
char AccountNumber[AN]={'\0'};
char psd[PN]={'\0'};
int i,errorcount=0;
while(1)
{
printf("\n请输入8位账号：");
for(i=0;i<8;i++)
AccountNumber[i]=getch();
printf("\n请输入6为密码：");
for(i=0;i<6;i++)
{
psd[i]=getch();
putchar('*');
}
if(isCorrect(AccountNumber,psd)==1)
{
int tag,amount;
while(1)
{
printf("\n欢迎登录银行账户管理系统，请选择您要的服务：1、查询余额；2、存款操作；3、取款操作；4、退出系统\n");
scanf("%d",&tag);
switch(tag)
{
case 1:
printf("您现在的余额为%f元\n",getBalance(AccountNumber));
break;
case 2:
printf("请输入您的存款金额：");
scanf("%d",&amount);
deposit(AccountNumber,amount);
printf("存款成功！您的当前余额为：%f元\n",getBalance(AccountNumber));
break;
case 3:
printf("请输入您的取款金额：");
scanf("%d",&amount);
if(amount<=getBalance(AccountNumber))
printf("取款成功！您的当前余额为：%f元\n",withdraw(AccountNumber,amount));
else
printf("取款失败！\n");
break;
case 4:
break;
}
if(tag==4)
break;
}

}
else
{
errorcount++;
if(errorcount==3)
{
printf("您已经连续三次输入错误，系统将自动关闭\n");
break;
}
}
}
}

⑸ C语言银行存储模拟系统

// t.cpp : Defines the entry point for the console application.//#include "stdafx.h"int Card[100][5+3];void main(){ for(int i=0;i<100;i++) { Card[i][0]=i; Card[i][1]=0; ]==nCahao) { nT=1; nPose=i; break; } } printf("卡号不正确"); } printf("你的存款余额为%d\n",Card[nPose][1]); while(1) { printf("1,取款 2, 存款\n"); int nSelect; scanf("%d",&nSelect); switch(nSelect) { case 1: printf("请输入提款金额\n"); int nJine; scanf("%d",&nJine); Card[nCahao][Card[nCahao][2]]=-nJine; Card[nCahao][2]=Card[nCahao][2]++; printf("你的取款额为%d请在出钞口领现金\n",nJine); nJine); printf("请取卡\n"); return; } } }

⑹ c语言中的一个经典问题 “模拟银行输出程序”（阿拉伯数字转大写汉字）

其实这种短路逻辑判断是你自己事先进行猜测的,在第一种情况下认为j==5出现的可能性比较高所以就把他放前面,同样else中也是这样,这种没多大的纠结必要

DOS下的？
