C++ Program to Find the Minimum and Maximum Element of an Array Last Updated : 17 Jan, 2023 Comments Improve Suggest changes Like Article Like Report Try it on GfG Practice Given an array, write functions to find the minimum and maximum elements in it. Example: C++ // C++ program to find minimum (or maximum) element // in an array. #include <bits/stdc++.h> using namespace std; int getMin(int arr[], int n) { int res = arr[0]; for (int i = 1; i < n; i++) res = min(res, arr[i]); return res; } int getMax(int arr[], int n) { int res = arr[0]; for (int i = 1; i < n; i++) res = max(res, arr[i]); return res; } int main() { int arr[] = { 12, 1234, 45, 67, 1 }; int n = sizeof(arr) / sizeof(arr[0]); cout << "Minimum element of array: " << getMin(arr, n) << " "; cout << "Maximum element of array: " << getMax(arr, n); return 0; } Output: Minimum element of array: 1 Maximum element of array: 1234 Time Complexity: O(n) Auxiliary Space: O(1), as no extra space is usedRecursive Solution Example: C++ // C++ program to find // minimum (or maximum) element // in an array. #include <bits/stdc++.h> using namespace std; int getMin(int arr[], int n) { // If there is single element, return it. // Else return minimum of first element and // minimum of remaining array. return (n == 1) ? arr[0] : min(arr[0], getMin(arr + 1, n - 1)); } int getMax(int arr[], int n) { // If there is single element, return it. // Else return maximum of first element and // maximum of remaining array. return (n == 1) ? arr[0] : max(arr[0], getMax(arr + 1, n - 1)); } int main() { int arr[] = { 12, 1234, 45, 67, 1 }; int n = sizeof(arr) / sizeof(arr[0]); cout << "Minimum element of array: " << getMin(arr, n) << " "; cout << "Maximum element of array: " << getMax(arr, n); return 0; } Output: Min of array: 1 Max of array: 1234 Time Complexity: O(n) Auxiliary Space: O(n), as implicit stack is used due to recursion Using Library functions: We can use min_element() and max_element() to find minimum and maximum of array. Example: C++ // C++ program to find minimum (or maximum) element // in an array. #include <bits/stdc++.h> using namespace std; int getMin(int arr[], int n) { return *min_element(arr, arr + n); } int getMax(int arr[], int n) { return *max_element(arr, arr + n); } int main() { int arr[] = { 12, 1234, 45, 67, 1 }; int n = sizeof(arr) / sizeof(arr[0]); cout << "Minimum element of array: " << getMin(arr, n) << " "; cout << "Maximum element of array: " << getMax(arr, n); return 0; } Output: Minimum element of array: 1 Maximum element of array: 1234 Time Complexity: O(n) Auxiliary Space: O(1), as no extra space is used Comment More infoAdvertise with us Next Article C++ Program to Find the Minimum and Maximum Element of an Array kartik Follow Improve Article Tags : Searching Recursion C++ Programs C++ DSA Arrays C++ Array Programs +3 More Practice Tags : CPPArraysRecursionSearching Similar Reads How to Find Minimum and Maximum Element of an Array Using STL in C++? Given an array of n elements, the task is to find the minimum and maximum element of array using STL in C++.ExamplesInput: arr[] = {1, 45, 54, 7, 76}Output: min = 1, max = 76Explanation: 1 is the smallest and 76 is the largest among all elements.Input: arr[] = {10, 7, 5, 4, 6}Output: min = 4, max = 3 min read C++ Program to Find the Second Largest Element in an Array In C++, an array is a data structure that is used to store multiple values of similar data types in a contiguous memory location. In this article, we will learn how to find the second largest element in an array in C++.
