How to Sort a String Vector in Dictionary Order in C++ ?

Answer

To sort a vector of strings in C++, you can use the sort function from the <algorithm> header.

✐ Examples

1 Sort String Vector in Dictionary Order

In this example,

We include the necessary headers: <vector> and <algorithm>.
We create a vector named vec and initialize it with some string values.
We use the sort function from the <algorithm> header to sort the elements of the vector in ascending order. By default, the sort function sorts elements in dictionary order.
Finally, we print the sorted vector to see the result.

C++ Program

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    std::vector<std::string> vec = {"banana", "apple", "orange", "grape"};
    std::sort(vec.begin(), vec.end());
    std::cout << "Sorted vector: ";
    for (const std::string& str : vec) {
        std::cout << str << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

Sorted vector: apple banana grape orange
