The purpose of the program is to find pairs of elements in the arr vector that sum up to a specific target value (sum in this case), which is set to 80. The program iterates through the vector, comparing each element with all subsequent elements to check if their sum equals the target value. When such a pair is found, it is printed to the console.

One of the important topics of Object Oriented Programming is Inheritance. Inheritance allows us to define a class in terms of another class, which allows us in the reusability of the code.Check out the code below:

class Triangle{
public:
void triangle(){
cout<<"I am a triangle\n";
}
};
The class Triangle has a function called triangle(). Now we create a class derived from the base class Triangle called Isosceles.

class Isosceles : public Triangle{
public:
void isosceles(){
cout<<"I am an isosceles triangle\n";
}
};
Now we can create a derived class object and use it to access the functions of the base class.

int main(){
Isosceles isc;
isc.isosceles();
isc.triangle();
return 0;
}
This code will print:

I am an isosceles triangle
I am a triangle
Now write a function in Isosceles class such that the output is as given below.

Sample Output

I am an isosceles triangle
In an isosceles triangle two sides are equal
I am a triangle

I will create different directories for different purpose.

So that all searching, sorting or any other algorithms are in different folders, making the user to navigate easily.

I would like to work on this issue.

You are given a main() function which takes a set of inputs. The type of input governs the kind of operation to be performed, i.e. concatenation for strings and addition for int or float. You need to write the class template AddElements which has a function add() for giving the sum of int or float elements. You also need to write a template specialization for the type string with a function concatenate() to concatenate the second string to the first string.

In this issue you have to make separate folders for different kind of platforms like gfg , codchef , hacker rank and different kind of other
By this any one can easily access the DSA problem.

@s7917 Can I contribute to this issue by adding a sorting method in c++, please assign me this

PROBLEM LINK- https://www.hackerrank.com/challenges/vector-sort/problem?isFullScreen=true

You are given N integers.Sort the N integers and print the sorted order.
Store the N integers in a vector.Vectors are sequence containers representing arrays that can change in size.

This program gives us the index of the two elements in array whose summation equals to the target value given by the user.

PROBLEM LINK - https://www.hackerrank.com/challenges/cpp-lower-bound/problem?isFullScreen=true

You are given N integers in sorted order. Also, you are given Q queries. In each query, you will be given an integer and you have to tell whether that integer is present in the array. If so, you have to tell at which index it is present and if it is not present, you have to tell the index at which the smallest integer that is just greater than the given number is present.

You are appointed as the assistant to a teacher in a school and she is correcting the answer sheets of the students.Each student can have multiple answer sheets.So the teacher has Q queries:

1 XY :Add the marks Y to the student whose name is X.

2 X: Erase the marks of the students whose name is X.

3 X: Print the marks of the students whose name is X. (If X didn't get any marks print 0.)
