valarray pow() function in C++ Last Updated : 06 Feb, 2023 Comments Improve Suggest changes Like Article Like Report The pow() function is defined in valarray header file. This function returns a valarray containing the results of the power operation on all the elements, in the same order. Syntax: pow(varr, n); Parameter: varr: This represents the valarray object.n: It represents a exponent value. Returns: This function returns a valarray containing the results of the power operation on all the elements. Below programs illustrate the above function: Example 1:- CPP // C++ program to demonstrate // example of pow() function. #include <bits/stdc++.h> using namespace std; int main() { // Initializing valarray valarray<int> varr = { -1, 2, 3, 4, -5 }; // Declaring new valarray valarray<int> varr1; // use of pow() function varr1 = pow(varr, 3); // Displaying new elements value cout << "The new valarray with" << " manipulated values is : " << endl; for (int& x : varr1) { cout << x << " "; } cout << endl; return 0; } Output:The new valarray with manipulated values is : -1 8 27 64 -125 Time complexity: O(N) Space complexity: O(1) Example 2:- CPP // C++ program to demonstrate // example of pow() function. #include <bits/stdc++.h> using namespace std; int main() { // Initializing valarray valarray<int> varr = { -1, 6, 3, 4, 5 }; // Declaring new valarray valarray<int> varr1; // use of pow() function varr1 = pow(varr, 2); // Displaying new elements value cout << "The new valarray with" << " manipulated values is : " << endl; for (int& x : varr1) { cout << x << " "; } cout << endl; return 0; } Output:The new valarray with manipulated values is : 1 36 9 16 25 Time complexity: O(N) Space complexity: O(1) Comment More infoAdvertise with us Next Article valarray pow() function in C++ bansal_rtk_ Follow Improve Article Tags : Misc C++ CPP-Functions cpp-valarray Practice Tags : CPPMisc Similar Reads valarray log() function in C++ The log() function is defined in valarray header file.
