Answer to Question #39660 in C++ for Theodore

Question #39660
Hello, I am studying C++ and fairly new at the language, I am trying to get a better understanding on how the following code works: #define MAX 1000 int main(){ char binaryNumber[MAX],hexaDecimal[MAX]; int temp; long int i=0,j=0; cout << "Enter any number any binary number: "; cin >> binaryNumber; while(binaryNumber[i]) { binaryNumber[i] = static_cast<int>(binaryNumber[i]) -48; ++i; } --i; while(i-2>=0){ temp = binaryNumber[i-3] * 8 + binaryNumber[i-2] * 4 + binaryNumber[i-1] * 2 + binaryNumber[i] ; if(temp > 9) hexaDecimal[j++] = temp + 55; else hexaDecimal[j++] = temp + 48; i=i-4; } if(i ==1) hexaDecimal[j] = binaryNumber[i-1] * 2 + binaryNumber[i] + 48 ; else if(i==0) hexaDecimal[j] = binaryNumber[i] + 48 ; else --j; cout << "Equivalent hexadecimal value: "; while(j>=0){ cout << hexaDecimal[j--]; }
