Task1: How the preprocessor will react when you try to use, #include<iostream.h> instead of #include?
Task2: How the preprocessor will react when you use cout but don't include #include in your code?
Task3: Take a char variable and use cin to take its value from the user, cout it and it will only return one character and loss rest of the data you have entered!
Task4: How to resolve above issue? [Hint: by using, getline(cin, line);]
add(int,int), add(float, float), both of these methods are in two different namespaces First and Second respectively.
Task1: Access these methods using scope resolution operator :: from main method?
Task2: Access these methods using "using" keyword for main method?
Task3: Try to access these methods without using, (SRO) and "using" keyword and check how the compiler will react to it?
Task4: Try to access these methods for Mixed Values [Int, Float] and see how the compiler will react to it?
Primary Data Types related questions in C++:
Task1: Initialise all primary data types, assign their values and print them all? [char, bool, short, int, long, float, double, long double, wide char]
String related Questions in C++:
Task1: What happens if we add integer with a string, how the compiler would react to it?
Task2: Check the entered string is Palindrome or not?
Task3: Make a reverse of a string using reverse method and reverse_iterator of string class?
Task4: String Compare: Check if the strings are equal or not? (do not use str1.compare(str2), do it manually)
Task5: String Compare: Check the possible values string.compare() function will return?
Task6: Check if string is mutable in C++ or not?
Array and 2D Array related Questions in C++:
Task-7.1 Create a switch statement [Manual], In Which:
a. When you pass 1 your program would print current year b. When you pass 2 your program would print current month c. When you pass 3 your program would print current day d. When you pass 4 your program would print Not applicable
Task-7.2 Create a switch statement [Using ctime], In Which:
a. When you pass 1 your program would print current year b. When you pass 2 your program would print current month c. When you pass 3 your program would print current day d. When you pass 4 your program would print Not applicable

Pointer, Function, Inline Function, Recursion in C++:
8.1 Task: Will the program through an error and if yes then why?
int *p = {10,20,20};
cout << *p;
p++;
cout << *p;
8.2 Task: Output of this program?
V1. Issue?
int arr[] = {10,20,30};
cout << *arr;
cout << arr;
arr++;
cout << *arr;

int arr[] = {10,20,30};
cout << *arr;
cout << arr;
cout << *(?);
8.3 Task: Output of this program?
