In this tutorial, we will be discussing a program to customize behavior for an uncaught exceptions in C++.Usually, the exception is handled by the try-catch block, but there are instances where there isn’t a matching catch block and the program just terminates. This terminate() function is modifiable as per user ... Read More

In this tutorial, we will be discussing a program to understand coroutines in C/C++.Coroutines are control instructions which switch the execution control between two routines which returning any of them.Example Live Demo#include int range(int a, int b){    static long long int i;    static int state = 0;    switch ...

In this tutorial, we will be discussing a program to count distinct consecutive sub-string of length two using C++ STL.For this we will provided with a string. Our task is to count and print all the unique substrings of length two from the given string.Example Live Demo#include using namespace std; void ... Read More

In this tutorial, we will be discussing a program to count inversions using set in C++ STL.Inversion count is a measure of how near the array is to be completely sorted. If the array is already sorted, the inversion count will be 0.Example Live Demo#include using namespace std; //returning inversion count ... Read More

In this tutorial, we will be discussing a program to count the number of 1’s and 0’s in a binary array using STL in C++.For this we will be provided with an array. Our task is to count the number of 0’s and 1’s present in the array.Example Live Demo#include ... Read More

In this tutorial, we will be discussing a program to count smaller elements on right side using set in C++ STL.For this we will be provided with an array. Our task is to construct a new array and add the number of smaller elements on the right side of the ... Read More

In this tutorial, we will be discussing a program to count smaller elements in sorted array in C++.In this we will be given a number and our task is to count all the elements present in the sorted array which are smaller than the given number.Example Live Demo#include using namespace ... Read More
