c语言做用户账单小程序,我自己编的一个c语言小程序:银行基本功能的实现
c语言是面向过程的,不像java,没有好看的界面,但是代码的执行效率很高.
没有用指针的,由于没有学到文件操作部分,涉及到存储的功能暂时无法实现,但是里面有修改密码的模块了.
独立想出来的,用了近六个小时.大部分花在了调试与界面美化上了.
#include
#include
static float balance=0.00; /*静态全局变量*/
static char password[10]="pengyuan";
void printstar(int Num) /*用于打印星号的自定义函数*/
{
int i;
for(i=0;i
printf("*");
}
void deposit(void) /*用于存款的函数模块*/
{ /*有些语句纯粹是为了美化下界面*/
float a1;
printf("/nPlease input the amount:/n");
scanf("%f",&a1);
balance+=a1;
printf("/n/nDeposit Successfully!");
printf(" **BANK OF CHINA**/n");
}
void withdraw(void) /*用于取款的函数模块*/
{
float a2;
printf("/nPlease input the amount:/n");
scanf("%f",&a2);
if(a2<=balance)
{
balance-=a2;
printf("/n/nWithdraw Successfully!");
printf(" **BANK OF CHINA**/n");
}
else printf("/nERROR! You Cannot Do It!");
}
void Balance(void) /*用于余额查询的函数模块*/
{
printf("/n/nBalance is %.2f",balance);
printf(" **BANK OF CHINA**");
if(balance<100)
{

printf("Please Deposit More Money!/n");
}
else if(balance>10000)
{
printf("/nYour Balance Is High!/n");
printf("For Safe Don't Deposit Any Money More!/n");
}
}
void change_password(void) /*用于修改密码的函数模块,可惜还没
