here << means shiftleft operation,>> means shiftright
operations x<<2 means 10<<2--->00001010<<2 take 8 binary
format.shiftleft means moving two places from leftmost to
rightmost i.e 00101000(40 will come),same like that x<<1
means 10<<1--->00001010<<1 after moving 00010100 answear
is:20,y>>2--->00010100>>2 after shiftright operation
00000101 answear is:5

//here Arrays class it is in util package to allow multiple
strings for print
System.out.println(Arrays.toString(java));
It can be determine by the help of number of byte we used in
the data type.
Ex:
char=1 byte
1 byte=8 bit
hence the range is 0-255
int
float
char
long
double
with the range and size
primary data type
user defined data type
derived data type
1 int,float,char,void
2 pointer array
3 enum struct union
You can pipe the value with delimiters like ! or ** or whatever is acceptable and then split and put in db later

The Programming Languages category on takluu.com is crafted for aspiring and experienced developers who want to showcase their core coding abilities during interviews. This section focuses on popular programming languages such as C, C++, Java, Python, JavaScript, Ruby, PHP, Go, Swift, and many others.
Programming languages are the fundamental building blocks for software and application development. Whether you’re building a mobile app, a cloud-based platform, or an embedded system, understanding how to write clean, efficient, and maintainable code is crucial. Interviewers often evaluate a candidate’s fluency in language syntax, data structures, object-oriented programming (OOP), memory management, error handling, and algorithmic problem-solving.
In this category, you’ll explore language-specific questions, including basic to advanced syntax, real-world coding challenges, debugging exercises, and performance optimization techniques. We cover best practices, design patterns, and language-specific nuances that often become deciding factors in technical interviews.
Additionally, many top tech companies emphasize problem-solving using a language of your choice, so the more comfortable you are with one or more languages, the better your chances of cracking the interview.
Whether you’re a beginner trying to master Python or an experienced developer preparing for system-level C++ interviews, this category has tailored resources to help you practice, revise, and get confident. You’ll also find tips on when to use which language, comparisons between programming paradigms, and key insights into what recruiters look for in language-specific roles.
By leveraging this category, you’ll be well-prepared for interviews ranging from junior software roles to senior backend engineers, mobile developers, and even full-stack specialists.
