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

In this tutorial, we will be discussing a program to understand core dump (segmentation fault) in C/C++.It happens due to reasons like when code tries to write on read only memory or tries to access corrupt memory location.ExampleModifying a string literalint main(){    char *str;    str = "GfG";   ... Read More

In this tutorial, we will be discussing a program to understand how to convert strings into numbers in C/C++.C/C++ provides two ways to convert strings into numbers.Example Live DemoUsing sscanf()#include int main(){    const char *str = "12345";    int x;    sscanf(str, "%d", &x);    printf("The value of x : ...
