cout<<"hexadecimal A4 + A5 = "< 
}
 
string addhex(string hex1, string hex2) { string result = " "; // setup result int sum = 0; // setup sum int i = hex1.length() - 1, j = hex2.length() - 1; while (i >= 0 || j >= 0 || sum == 1){ sum += ((i >= 0)? hex1[i] - '0': 0); // get sum for i sum += ((j >= 0)? hex2[j] - '0': 0); // get sum for j result = char(sum % 16 + 'A') + result; sum /= 16; // get carry i--; j--; // move to next one } return result; } 
 
Please help me to fix me code, I am having problem to fix it in C++
