You have c++. Use proper containers (e.g. std::vector).

#include 
#include 
#include 
using namespace std;

void WordReplace(vector &sentence, string search_string,
             string replace_string) {
    for (auto &word : sentence) {
        if (word == search_string)
            word = replace_string;
    }
}

int main() {
    vector sentence{"I", "don't", "hate", "c++"};

    for (const auto word : sentence)
        cout << word << " ";
    cout << endl;

    WordReplace(sentence, "hate", "love");

    for (const auto word : sentence)
        cout << word << " ";
    cout << endl;

     return 0;
}

or even better, don't reinvent the wheel

std::vector x {"I", "don't", "hate", "c++"};
std::replace( x.begin(), x.end(), "hate", "love" );
