How can I reve开发者_JAVA百科rse a character array? Like this:

char word1[10] = "this"; 
char word2[10] = word1[10] // in reverse 
cout<<word2; // I want it to output "siht"

---

std::string word1 = "this";
std::string word2 = word1;
std::reverse(word2.begin(), word2.end());
std::cout << word2;

---

How about a simple loop (since i do not know the exact type of word1 and word2)?

for (int i = 0, k = 9; i < 10; i++, k--) {
    word2[k] = word1[i];
}

I highly suggest that you use std::string instead of char. There are plenty of answers on how to do this with std::string here.

---

I'd hazard something like the following:

1. Copy word1 to word2, using std::copy
2. std::reverse with word2 begin to end

and now word2 contains reverse, can't say more without knowing types.

---

Use a string reverse function to perform the same.

---

If word1 and word2 are char arrays, then nope. If instead word1 and word2 were some sort of object with a capacity of 10, you could just override the assignment operator.

---

int main(int, char**) {
    std::string word1 = "beef";
    std::string word2(word1.rbegin(), word1.rend());
    std::cout << word2;
}

std::reverse_copy(word1, word1+10, word2);
