XOR of all Prime numbers in an Array in C++
In this problem, we are given an array of n elements. Our task is to print xor of all prime numbers of the array.Let’s take an example to understand the problem,Input − {2, 6, 8, 9, 11}Output −To solve this problem, we will find all the prime numbers of the array and the xor them to find the result. To check if the element is prime or not, we will use sieve’s algorithm and then xor all elements that are prime.ExampleProgram to show the implementation of our solution,#include
Read Morestrchr() function in C++ and its applications
In this article, we will be discussing the working, syntax, and examples of strchr() function in C++ STL.What is strchr()?strchr() function is an inbuilt function in C++ STL, which is defined in the header file. strchr() function is used to find when the character first occurred in the string. This function returns the pointer to the location where the character first appeared in the string.If the character doesn’t exist in the string the function returns the null pointer.Syntaxchar* strchr( char* str, char charac );ParametersThe function accepts the following parameter(s)−str − It is the string in which we have to ...

In this article, we will be discussing the working, syntax, and examples of ilogb() function in C++.What is ilogb()?ilogb() function is an inbuilt function in C++ STL, which is defined in iostream> using namespace std; int main(){ int output, var = 2; output = ilogb(var); cout
Read Moreratio_equal() in C++ with example
In this article, we will be discussing the working, syntax, and examples of ratio_equal() function in C++ STL.What is ratio_equal template?ratio_equal template is inbuilt in C++ STL, which is defined in header file. ratio_equal is used to compare the two ratios. This template accepts two parameters and checks whether the given ratios are equal or not. Like we have two ratios, 1/2 and 3/6 which are equal when we simplify them but the numbers are not equal so C++ has an inbuilt template to check whether the two ratios are equal or not and return true if they are ...
Read Morelogical_and in C++
In this article, we will be discussing the working, syntax, and examples of logical_and function object class in C++.What is logical_and?logical_and binary function is an inbuilt binary function object class in C++, which is defined in a header file. logical_and is a binary function used to give the result of logical “and” operation between two arguments.Logical AND is the binary operation that returns true only and only if both the binary values are true.Syntax of logical_andTemplate struct logical_and : binary_function { T operator() (const T& a, const T& b) const {return a&b&; } };Template parametersThe function accepts the ...

In this article, we will be discussing the working, syntax, and examples of modulus functions in C++.What is modulus function C++?modulus function object class in C++, which is defined in header file. modulus function is a binary function object class used to get the result of the modulus operation of the two arguments. This function works the same as the operator ‘% ‘.Syntax of modulus functionTemplate struct modulus : binary_function { T operator() (const T& a, const T& b) const {return a%b; } };Template parametersThe function accepts the following parameter(s) −T − This is the type of the ...
Read MoreRaw string literal in C++ program
In this article, we will be discussing the raw string literal in C++, its meaning, and examples.There are escape characters in C++ like “” or “\t”. When we try to print the escape characters, it will not display on the output. To show the escape characters on the output screen we use a raw string literal by using R”(String with escape characters)”. After using R in the front of the string the escape character will be displayed on the output.ExampleLet’s understand this with the help of an example#include using namespace std; int main(){ string str = "tutorialspoint" ; ...
Read MoreTriangle in C++
Suppose we have a triangle. We have to find the minimum path sum from top to the bottom. In each step, we can move to adjacent numbers on the row below.For example, if the following triangle is like[ [2], [3, 4], [6, 5, 7], [4, 1, 8, 3] ]The minimum path sum from top to bottom is 11 (2 + 3 + 5 + 1 = 11).Let us see the steps −Create one table to use in Dynamic programming approach.n := size of trianglefor i := n – 2 down to 0for ...
Read MoreOnline Stock Span in C++
Suppose we have an API, that collects daily price quotes for some stock, and returns the span of that stock's price for the current day. Here the span of the stock's price today is defined as −The maximum number of consecutive days (starting from today and going backwards) where the price of the stock was less than or equal to today's price.For example, if we see 7 days stock share records like [100, 80, 60, 70, 60, 75, 85], then the stock spans would be [1, 1, 1, 2, 1, 4, 6]. We have to write the actual module for ...
Read MoreFruit Into Baskets in C++
Suppose we have a row of trees, the i-th tree produces fruit with type tree[i]. we can start at any tree of our choice, then repeatedly perform these steps −Add one piece of fruit from this tree to our baskets. If there is no chance, then stop.Move to the next tree to the right of the current one. If there is no tree to the right, then stop.We have two baskets, and each basket can carry any quantity of fruit, but we want each basket should only carry one type of fruit each. We have to find the total amount ...
