代码说明:

  ree(void *p)函数是用来释放程序动态申请的内存。其参数是个指针类型。在C当中,只有当使用了动态内存申请函数malloc calloc realloc申请内存之后,才可以使用free来释放之。释放之后就不能再使用了。(ree (void* p) function is used to release the program dynamically allocated memory. Its argument is a pointer type. In C, only apply when using the dynamic memory functions malloc calloc realloc application memory before you can use free to release it. After release no longer use.)

    有一存储很多商品数据(每件商品的属性先后包括:品名、规格、单价(有小数位)、数量,数据的最长长度分别为20、10、6、5,在文件中以空格为分隔,每个商品的数据占一行)的文本文件,从键盘输入某种商品的品名,要求在文件中查找有无相应品名商品(可能有多条记录或没有),若有则在屏幕上显示出相应的商品的品名、规格、数量、单价(显示时,品名、规格、数量、单价之间使用逗号(,)作分隔,单价显示时只显示2位小数),若无则显示没有相应品名的商品。 (There are a lot of goods stored data (each item has the attributes include: name, size, price (with decimal places), quantity, the maximum length of the data were 20,10,6,5, a space in the file is separated The data for each item per line) text file, input from the keyboard of a commodity name, asked whether the corresponding file for the product name (may be multiple records or did not), if it is displayed on the screen of the corresponding product name, size, quantity, unit price (display, name, size, quantity, unit price between a comma (,) as a separator, price display shows only two decimal places), if not then show no corresponding product name .)

  • 定时时钟
    “S7”键复位,时钟显示,数码管的1、2位为秒钟,3、4位为分钟, 通过按键1和2可分别设置时钟的秒钟和分钟值,当按下按键3时,可以暂停/启动;利用按键4可进行定时时钟设置,按一下,则秒钟闪烁,利用按键3设置定时时钟的秒钟值;再按按键4,则分钟闪烁,设置定时时钟的分钟值;按下按键4,则确认定时时钟并退出设置,正常显示时钟。 当时钟值与定时值相等时(此值不为0),数码管快速闪烁报警,延时十秒,然后结束报警正常显示时钟。(When the clock value is equal to the fixed time value (this value is not 0), digital tube quick flashing alarm, delay 10 seconds, and then end the alarm normal display clock.)
