ProgramGuruTo check if a specified element is present in an array in C++, you can use methods like find or a loop to iterate through the array and compare each element.
In this example,
numbers with values 10, 20, 30, 40, 50.find method to check if element 30 is present in the vector.find method returns an iterator to the element if found, otherwise it returns the end iterator.#include <iostream>
#include <vector>
#include <algorithm>
int main() {
std::vector<int> numbers = {10, 20, 30, 40, 50};
int element = 30;
auto it = std::find(numbers.begin(), numbers.end(), element);
bool isPresent = it != numbers.end();
std::cout << "Element 30 is present: " << std::boolalpha << isPresent << std::endl;
return 0;
}Element 30 is present: true
In this example,
fruits with values 'apple', 'banana', 'cherry'.for loop to iterate through the array and compare each element with the specified element 'banana'.found to true; otherwise, it remains false.#include <iostream>
#include <string>
int main() {
std::string fruits[] = {"apple", "banana", "cherry"};
std::string element = "banana";
bool found = false;
for (const auto& fruit : fruits) {
if (fruit == element) {
found = true;
break;
}
}
std::cout << "Element 'banana' is present: " << std::boolalpha << found << std::endl;
return 0;
}Element 'banana' is present: true
In this tutorial, we learned How to check if Specified Element is present in the Array in C++ language with well detailed examples.
