In this C++ program, we implement Sorting containers in STL.Functions and descriptions:Functions used here: l.push_back() = It is used to push elements into a list from the front. l.sort() = Sorts the elements of the list. Where l is a list object.Example Code#include #include #include #include using namespace std; int main() { list l; list::iterator it; int c, i; while (1) { cout
Read MoreDifference between while(1) and while(0) in C/C++
Here we will see what are the differences between while(1) and while(0) in C or C++. The while is a loop of C or C++. Using this loop we can check one condition, and the statements inside the loop will be executed while the condition is true.The while(1) or while(any non-zero value) is used for infinite loop. There is no condition for while. As 1 or any non-zero value is present, then the condition is always true. So what are present inside the loop that will be executed forever. To come out from this infinite loop, we have to use ...

Read MoreC++ Program to Search Sorted Sequence Using Divide and Conquer with the Aid of Fibonacci Numbers
In this C++ program we implement a Divide and Conquer approach using Fibonacci numbers. Using Fibonacci numbers, we calculate mid of data array to search the data item. The time complexity of this approach is O(log(n)).AlgorithmBegin Assign the data to the array in a sorted manner. Take input of the element to be searched. Call FibonacciSearch() function. Calculate the mid value using ‘start+fib[index-2]’ expression. If the chosen item is equal to the value at mid index, print result and return to main. If it is lesser than the value at mid index, proceed with ...
