A void pointer, also known as a generic pointer, is a pointer that is not associated with any specific data type, making it suitable for pointing to any type of data. In other words, avoid pointercan point to an integer, a character, a string, or any other data type. This flexibility...
#include <iostream> class MyClass { public: MyClass() { std::cout << "Constructor called!" << std::endl; } }; int main() { MyClass obj; return 0; } In this, we’ve retained the essential parts of the previous example while removing unnecessary whitespace and comments. The output...
Learn: What is the difference between cout and std::cout, how to use cout's different forms? How can we use cout with and without using 'std::'? cout and std::cout both are same, but the only difference is that if we use cout, namespace std must be used in the program or if...

Example of <bits.stdc++.h> #include <bits/stdc++.h> using namespace std; int main(){ vector<int>v ={1,2,3,4,5}; sort(v.begin(), v.end()); for(int i : v){ cout<<i<<" "; } cout<<endl; return0; } In the above code, the <bits/stdc++.h> header file is used....

From cppreference :- In the context of a direct-initialization, a bool object may be initialized from a prvalue of type std::nullptr_t, including nullptr. The resulting value is false. However, this is not considered to be an implicit conversion. The conversion is only allowed for direct-...
