C language I work 10: a job for Week

A week teaching content & goals

  • Chapter 4 describes the circulation loop structure 4.5 overall structure of the program design, involve multiple typical algorithms. Students can be based on the actual situation, select the appropriate algorithm, reasonable loop structure, programming skilled.

    Second, this week the head job

This work belongs to the curriculum C Programming Language II
Where the job requires Work requirements
My aim in this course is Control loop structure and more typical algorithms
This job helped me achieve that goal in terms of specific By job and get feedback from their own problems found during analysis solution
references literature

Third, the work week

1.PTA lab assignments

1.1 Title: The title requires programming, the output from the n-th row begins uppercase A triangular array of the character.

  • 1.1.1 Data processing
    data expressed: with the n, number, i, j variables, is an integer type.
    data processing:

    The main function
    defined integer variable n, number, i, j
    calling function scanf ( "% d", & n)
    using for loop for (i = n; i> 0; i--) if i = n, and represents i> 0 i is to be reduced. 1
    for (J = 0; J <i; J ++) indicates j = 0, j <i is J plus. 1
    the printf ( "% C", 'A' + Number); Print 'A' + Number
    Number ++ ;
    printf ( "\ the n-");

  • 1.1.2 Screenshot experiment code
  • 1.1.3 build test data

  • 1.1.4 PTA submit a list and description of

    compilation errors: for loop written semicolon comma, no increase after printf ";"

    1.2 Title:

  • 1.2.1 数据处理
    数据表达:result,n,i,j,f整型
    数据处理:

    主函数int main()
    定义整型result,n,i,j,f=0;
    调用函数scanf("%d",&n);
    for(i=2;i<=n;i++)
    result=pow(2,i)-1;
    for(j=2;j<=sqrt(result);j++)for循环
    if(result%j==0) break;跳出循环
    if(j>sqrt(result))
    printf("%d\n",result);
    f++;f加1
    if(f==0)
    printf("None");

  • 1.2.2 实验代码截图
  • 1.2.3 造测试数据

  • 1.2.4 PTA提交列表及说明

    编译错误:题目没看懂
    部分正确:没有考虑素数

    2.代码互评

  • 同学代码
  • 我的代码

评:同学代码利用的是if循环里面嵌有while及for循环语句,知识涵盖比较丰富,而我的代码里面只有for循环里嵌入for循环显得很单调入门

3.学习总结

3.1 学习进度条

周/日期 这周所花时间 代码行 学到的知识点简介 目前比较迷惑的问题
10/9-10/12 两天 87行 整型和浮点型,printf,scanf语句,运算符等 不知道空格什么时候用
10/16-10/18 一天 90行 for循环语句 for语句里面的分号容易遗漏
10/23-10/25 20小时 89行 调用函数 还没搞清楚调用函数的意义是什么
10/30-11/2 25小时 120 四则运算的运用,字符型 大括号应该怎么打
11/6-11/8 2天 126 switch语句 题目不会做
11.11-11.17 10小时 190 熟悉使用while和do-while结构解决问题 题目不会做
11-20--11-22 10h 191 continue和break语句,嵌套循环 题目不会做
11/27-11/29 一天 120+ 循环嵌套 题目不会做

3.2 累积代码行和博客字数

3.3 学习内容总结和感悟

  • 3.3.1 学习内容总结

  • 3.3.2 学习体会
  • 学习循环结构,自我感觉还是很有趣的。循环结构的程序设计,涉及到多个典型算法,又让我开眼界,目前没有什么好疑惑的除了题目不会做,最主要的是比以前要好很多,会很多。
