balance 为 main（）的局部变量



#include<stdio.h>#include<stdlib.h>#include<conio.h>void menu();int deposit(int balance);int withdraw(int balance);void check(int balance);void quit();void main(){    int balance=500;    int menuNumber=0;    while(menuNumber!=4)//当按菜单4时退出循环    {      menu();      scanf("%d",&menuNumber);       switch(menuNumber)     {     case 1:balance=deposit(balance);break;     case 2:balance=withdraw(balance);break;     case 3:check(balance);break;     case 4:quit();break;     default :printf("operator wronng!\n");     }            }  }//0 menuvoid menu(){    system("color 37");  //change the color of screen and text   printf("*****************************\n");   printf("* Menu:                     *\n");   printf("* 1.Deposit                 *\n");   printf("* 2.Withdraw                *\n");   printf("* 3.Check Balance           *\n");   printf("* 4.Quit                    *\n");   printf("*****************************\n");   printf("Enter Your Choice:");       }//1 depositint deposit(int balance){  int amount,newbalance;  printf("Enter the amount to Deposit:");  scanf("%d",&amount);  newbalance=balance+amount;  printf("Your balance is %d RMB\n",newbalance);  return newbalance;}//2 withdrawint withdraw(int balance){  int amount,newbalance;  printf("Enter the amount to withdraw:");  scanf("%d",&amount);  newbalance=balance-amount;  if(newbalance<0)  {      printf(" Sorry InSufficient Balance!!!!\n");      return balance;  }else  {  printf("Now your balance is %d RMB\n",newbalance);  return newbalance;  }}//3 check  void check(int balance){      printf("Your balance is %d RMB\n",balance);    } //4 quit  void quit(){      system("cls");   printf("Thank YOu for Using my BANK!!!!\n");  }

若balance为全局变量，代码如下：
#include<stdio.h>#include<stdlib.h>#include<conio.h>void menu();void deposit();void withdraw();void check();void quit();int balance=500;void main(){        int menuNumber=0;    while(menuNumber!=4)//当按菜单4时退出循环    {      menu();      scanf("%d",&menuNumber);       switch(menuNumber)     {     case 1:deposit();break;     case 2:withdraw();break;     case 3:check();break;     case 4:quit();break;     default :printf("operator wronng!\n");     }            }  }//0 menuvoid menu(){    system("color 37");  //change the color of screen and text   printf("*****************************\n");   printf("* Menu:                     *\n");   printf("* 1.Deposit                 *\n");   printf("* 2.Withdraw                *\n");   printf("* 3.Check Balance           *\n");   printf("* 4.Quit                    *\n");   printf("*****************************\n");   printf("Enter Your Choice:");       }//1 depositvoid deposit(){  int amount;  printf("Enter the amount to Deposit:");  scanf("%d",&amount);  balance=balance+amount;  printf("Your balance is %d RMB\n",balance);  }//2 withdrawvoid  withdraw(){  int amount,newbalance;  printf("Enter the amount to withdraw:");  scanf("%d",&amount);  newbalance=balance-amount;  if(newbalance<0)  {      printf(" Sorry InSufficient Balance!!!!\n");       }else  {     balance=newbalance;     printf("Now your balance is %d RMB\n",balance);   }}//3 check  void check(){      printf("Your balance is %d RMB\n",balance);    } //4 quit  void quit(){      system("cls"); //clear the screen   printf("Thank YOu for Using my BANK!!!!\n");  }
