How to check if Specified Element is present in the Array in C++ ?

Answer

To 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.

✐ Examples

1 Check if Element 30 is present in Integer Array using find

In this example,

We create a vector named numbers with values 10, 20, 30, 40, 50.
We use the find method to check if element 30 is present in the vector.
The find method returns an iterator to the element if found, otherwise it returns the end iterator.

C++ Program

#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;
}

Output

Element 30 is present: true

2 Check if Element 'banana' is present in String Array using loop

In this example,

We create a string array named fruits with values 'apple', 'banana', 'cherry'.
We use a for loop to iterate through the array and compare each element with the specified element 'banana'.
If the element is found, we set a boolean variable found to true; otherwise, it remains false.

C++ Program

#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;
}

Output

Element 'banana' is present: true
