Uninitialized variables

By Md Shoriful Islam

 Uninitialized variables

Unlike some programming languages, C/C++ does not initialize most variables to a given value (such as zero) automatically. Thus when a variable is given a memory address to use to store data, the default value of that variable is whatever (garbage) value happens to already be in that memory address! A variable that has not been given a known value (usually through initialization or assignment) is called an uninitialized variable.

## Enhancing Internet Speed Through CMD Commands To improve your internet connection using cmd, you can leverage several built-in Windows features. These include managing DNS cache, pinging the default gateway, and adjusting TCP settings with the `netsh int tcp` command. When facing a slow internet connection, the usual first step is to restart the device or router. If this doesn't resolve the issue, reaching out to the ISP is the next step. If the problem persists even after contacting the ISP, some users might consider changing their service provider. To potentially avoid these steps, here are some strategies for boosting your internet speed using cmd. ### How to Improve Internet Speed Using CMD? There are numerous built-in Windows commands and tools that can address common issues like slow internet.

Bitwise Operators in C/C++

  Bitwise Operators in C/C++ In C, the following 6 operators are bitwise operators (also known as bit operators as they work at the bit-level). They are used to perform bitwise operations in C. The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. The | (bitwise OR) in C or C++ takes two numbers as operands and does OR on every bit of two numbers. The result of OR is 1 if any of the two bits is 1. The ^ (bitwise XOR) in C or C++ takes two numbers as operands and does XOR on every bit of two numbers. The result of XOR is 1 if the two bits are different. The << (left shift) in C or C++ takes two numbers, the left shifts the bits of the first operand, and the second operand decides the number of places to shift. The >> (right shift) in C or C++ takes two numbers, right shifts the bits of the first operand, and the second operand decides the number of places to shift. The ~...
