今天贴两个程序。
1.ATM取款机

2.猜数字游戏

#include <stdio.h>

void main()

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 )
    {

    }
    else if( Number > 30 && Number <= 50 )
    {

    }
    else
