GIT Notes for the Interview PART-2

After the basics of GIT like cloning the repository, creating a branch in the previous post, now we will look at how to add files, commit and push your changes.

Once you are done with writing your code or changes to existing code or module, you need to add files that you have changed into the staging area

To check which files you need to add, write this command

git status

This command is used to check the current status of your local branch, which files are ready to be committed, and which files need to be added to the staging area for commit.

You will see some files in Red color

modified : folder/xyz/abc.cpp

This file is not added to the staging area, so you need to add the files using the command

git add folder/xyz/abc.cpp

Once you are done with adding the file in the staging area, your file is ready for the commit. For commit use the following command

git commit -m "Added condition for denominator not equal to zero in abc.cpp"

here you can use -m and comment in double-quotes about the code/change you have added.

After you have committed your code locally, its time to push your changes to the remote repository so that other developers can use your changes.

But before pushing, you need to pull the latest changes made by developers on the remote repository, so that your local repository is in sync with the remote repository and then you push your changes thus avoiding any conflicts and issues. You can use the below commands in the given order

git pull
git push

Note that you can only use the above commands directly when your local branch is tracking the remote branch already. If your local branch is not tracking the remote branch then these commands will not work.

We will see more about remote-tracking branches and how to create them in my next post.

Here is the link to the post where we discussed about remote-tracking branches

Tricky Questions or Puzzles in C ( Updated for 2026)

Updated for 2026 This article was originally written when C/C++ puzzles were commonly asked in interviews. While such language-specific puzzles are less frequent today, the problem-solving and logical reasoning skills tested here remain highly relevant for modern Software Engineering, Data Engineering, SQL, and system design interviews . Why These Puzzles Still Matter in 2026 Although most Software &   Data Engineering interviews today focus on Programming, SQL, data pipelines, cloud platforms, and system design , interviewers still care deeply about how you think . These puzzles test: Logical reasoning Edge-case handling Understanding of execution flow Ability to reason under pressure The language may change , but the thinking patterns do not . How These Skills Apply to Data Engineering Interviews The same skills tested by C/C++ puzzles appear in modern interviews as: SQL edge cases and NULL handling Data pipeline failure scenarios Incremental vs ...

Decorators in Python

Decorators provide additional functionality to the functions without directly changing their definition of them. Basically, it takes the functions as an argument, adds functionality to them, and returns it.  Before diving deep into the concept of Decorators, let's first try to understand  What are functions in Python and what is an inner function? In Python everything is Objects, be it Class, Variables, and Functions . So functions are python first-class objects that can be used or passed as an argument. You can store the functions in variables, you can pass a function to another function as parameters, and you can also return the function from the function. Below is one simple example where we are treating functions as objects . def make_me_lowercase ( str ): return str .lower() print (make_me_lowercase( "HELLO World" )) copy_of_you = make_me_lowercase print (copy_of_you( "HELLO World" )) The output of the above calls for both the functio...

Program to uncompress a string ie a2b3c4 to aabbbcccc

Below is the program to uncompress a string #include<stdio.h> #include<conio.h> #include<stdlib.h> int main() { char str[100]="a2b3c4d8u7"; for(int i=0;str[i]!='\0';i++) { if(i%2!=0) { for(int j=0;j<atoi(&str[i]);j++) { printf("%c",str[i-1]); } } } getch(); } Want to become a Data Engineer?
