It's the shortest and simplest way to write in C++.

#include <algorithm>
std::reverse(str.begin(), str.end());

Use the variable intc temporarily to exchange the front and back values, as in swapping.

void reverse(char s[])
{
    int length = strlen(s) ;
    int c, i, j;

    for (i = 0, j = length - 1; i < j; i++, j--)
    {
        c = s[i];
        s[i] = s[j];
        s[j] = c;
    }
}
