摘要：在第七章的学习当中我明白了如何设计投票情况统计的程序。知道了定义一个数组，需要明确数组变量名，数组元素的类型和数组的大小。例如int a[……]是定义一个有……个整形元素的数组 char c[……]是定义一个有……个字符形元素的数组 float f[……]是定义一个有……个单精度浮点新元素的数组了解了在找出矩阵中最大值所在的位置的程序设计中，如果用变量row和col分别记录最大值的行下标和列下标，则最大值就是a[row][col]二维数组的初始化方法有“分行赋初值”和“顺序赋初值”两种。等知识

摘要：通过第五章的学习我学会了如何设计计算圆柱体积的程序。如何实现数字金字塔，如何完成复数运算。函数是一个完成特定工作的独立程序模块，它包括由scanf-s（），printf（）组成的库函数和由cylinder（），fact（）组成的自定义函数。函数是由函数首部和函数体构成的。在输入数字金字塔程序时”%d”中d”中间要加空格。不然金字塔会变成直角三角形。

摘要：通过第三章的学习我学会了如何设计简单的猜数游戏，四则运算和查询自动售货机中商品的价格等程序。学会了用if-else语句和省略else的if语句来表达二分支结构。 实现多分支结构的方法是if-else语句。 字符型变量再定义时用类型名为char。调用函数scanf_s（）和printf（）来输入和输出字符。知道了switch的多种形式，如在switch语句的每个语句段中都使用break语句。 在switch语句中不使用break语句。 在switch语句的某些语句段中使用break语句。明白了如何运用多分支结构编写四则运算程序

摘要：通过第一章的学习我知道了设计一个C语言程序的基本步骤，并能编写一个求解过程的程序。了解了程序设计语言的功能与语法。C语言的发展历史与特点。也明白了“int i,sum=0;"定义了两个整数类型（int)i和sum，同时把sum初值赋为0.for(i=1;i<=100;i++)是一个循环"if(i%2==0)sum=sum+i;"表示：如果i是偶数，就将i累加到sum中。
