cshift() function for valarray in C++ Last Updated : 23 Oct, 2018 Comments Improve Suggest changes Like Article Like Report The cshift() function is defined in valarray header file. This function returns a new valarray of the same size with elements whose positions are shifted circularly by n elements. If n is negative, right-shift is applied, if n is positive left-shift is applied. Syntax: valarray cshift (int n) const; Parameter: n: It represents the number of element to shift. Returns: This function returns the new valarray after circularly shifting elements. Below programs illustrate the above function: Example 1:- CPP // C++ program to demonstrate // example of cshift() function. #include <bits/stdc++.h> using namespace std; int main() { // Initializing valarray valarray<int> varr = { 3, 2, 5, 4, 1 }; // Declaring new valarray valarray<int> varr1; // using cshift() to shift elements to left // shifts valarray by 3 position varr1 = varr.cshift(3); // Displaying elements of valarray after shifting cout << "The new valarray after shifting is = "; for (int& x : varr1) cout << x << " "; cout << endl; return 0; } Output: The new valarray after shifting is = 4 1 3 2 5 Example 2:- CPP // C++ program to demonstrate // example of cshift() function. #include <bits/stdc++.h> using namespace std; int main() { // Initializing valarray valarray<int> varr = { 3, 2, 5, 4, 1 }; // Declaring new valarray valarray<int> varr1; // using cshift() to shift elements to right // shifts valarray by 3 position varr1 = varr.cshift(-3); // Displaying elements of valarray after shifting cout << "The new valarray after shifting is = "; for (int& x : varr1) cout << x << " "; cout << endl; return 0; } Output: The new valarray after shifting is = 5 4 1 3 2 Comment More infoAdvertise with us Next Article cshift() function for valarray in C++ bansal_rtk_ Follow Improve Article Tags : Misc C++ Programs C++ CPP-Functions cpp-valarray +1 More Practice Tags : CPPMisc Similar Reads max() function for valarray in C++ The max() function is defined in valarray header file.
