今天贴两个程序。

1.ATM取款机

#include <stdio.h>

void main()“

2.猜数字游戏

#include <stdio.h>

void main()

{

int Password=0,Number=0,price=58,i=0;

while( Password != 1234 )
{
if( i >= 3 )
return;
i++;
puts("Please input Password: ");
scanf("%d",&Password);
}

i=0;
while( Number!=price )
{
do{
puts("Please input a number between 1 and 100: ");
scanf("%d",&Number);
printf("Your input number is %d\n",Number);
}while( !(Number>=1 && Number<=100) );
if( Number >= 90 )
{
printf("Too Bigger! Press any key to try again!\n");
}
else if( Number >= 70 && Number < 90 )
{
printf("Bigger!\n");
}
else if( Number >= 1 && Number <= 30 )
{
printf("Too Small! Press any key to try again!\n");
}
else if( Number > 30 && Number <= 50 )
{
printf("Small! Press any key to try again!\n");
}
else
{
if( Number == price )
{
printf("OK! You are right! Bye Bye!\n");
}
else if( Number < price )
{
printf("Sorry,Only a little smaller! Press any key to try again!\n");

}
else if( Number > price )
printf(" Sorry, Only a little bigger! Press any key to try again!\n");
}
getch();
}

}
