Learning Log

Day 3: February 3, 2022

What I learned today:

• Built a Scratch application - Shootout.

• Tried to understand cpp classes and objects.

• Tried to understand cpp namespace for using same variable or function again by initializing them in different namespaces and header files used to contain all the declarations.

• Explored about back end development.

  • working with servers and databases and their effective communications.

  • Got a road-map.

• Tried to understand about threads, sharing same memory space, user threads(not considered by OS scheduler as separates processes), kernel threads(considered by OS scheduler as separate processes) race conditions, critical states, locks, locking mechanism, spinlocks, sleeping mutex.

• Explored about Devops.

  • Software development practices for continuous collaboration and communication among devops teams to develop, test and deploy softwares quickly and speedup feedback cycles inturn increasing customer satisfaction.

  • Got a road-map.

• Explored about SAP and MVP.

What I learned today:

• Leetcode problem - using XOR to cancel out two similiar elements in array - Single Number

• Implemeted Array data structure

  • structure - to club different data types into one

  • assert - to constraint the input to follow the condition

  • template - used to set template data types

    • template <typename T> // initializes only on compile time
      class example {
      	T arr[];
      }

  • Reference vs Pointer

    • Reference has the same address but different name
    • int a = 3;
    • int &b = a;
    • Pointer can point to different addresses
    • int a = 3;
    • int b;
    • b = &a;

  • C vs C++

    • Structural vs Structural and Procedural
    • C is almost a subset of Cpp since it started getting into different unique paths of development
    • Taking advantage C light-weightedness into Cpp will be helpful

  • Member Initializer list

    When you initialize fields via Member initializer list the constructors will be called once and the object will be constructed and initialized in one operation.

    If you use assignment then the fields will be first initialized with default constructors and then reassigned (via assignment operator) with actual values.

  • Bracket matching problem
