In C++, when working with `std::vector` to find elements using custom comparators on embedded targets, you can utilize algorithms like `std::find_if` or `std::find` in combination with a custom comparator. This approach is efficient for embedded systems where resources are limited. Below is an example that demonstrates how to accomplish this.

Learn how to efficiently find elements in a std::vector using custom comparators in C++, suitable for embedded systems applications.

struct CustomComparator {
bool operator()(int a, int b) {
return a < b; // Custom comparison logic
}
};
int main() {
std::vector numbers = {10, 20, 30, 40, 50};
int target = 30;
// Using std::find_if with custom comparator
auto it = std::find_if(numbers.begin(), numbers.end(),
[&target](int value) {
return value == target;
});
if (it != numbers.end()) {
std::cout << "Found: " << *it << std::endl;
} else {
std::cout << "Not Found" << std::endl;
}
return 0;
}
