Thread: Rearranging a string... and a glitch

I finally got my code to work. Just uncomment out the lines that are commented to add back in the functionality that i don't have, if they are needed.

Code:

#include <iostream>
#include <conio.h>  // getche();

int main(int argc, char *argv[])
{
  char sInput[1024];

  int iLength = 0;
  int i = 0, x = 0, y = 0, z = 0;

  cout << "What message do you want to scramble?\n";
  cin.get(sInput, 1024);
  //cin.ignore(1024, '\n');  // Do you really need this?

  iLength = strlen(sInput);
  int half = iLength/2;
  //strrev(sInput);            // I don't have this function, sorry.

  char *sOutput = new char[iLength];
  for(int p=0;p<iLength;p++)sOutput[p]='-';
  sOutput[iLength]='\0';
  for (i=0, x=0; (i<iLength) && (sInput[x] != '\0'); i++, x=i/2){
    if (i%2==0){
      sOutput[half+x]=sInput[i];
    } else {
      sOutput[x]=sInput[i];
    }
  }
  cout << "Scrambled:   " << sOutput << endl;
  for (i=0, x=0; (i<iLength) && (sInput[x] != '\0'); i++, x=i/2){
    if (i%2==0){
      sInput[i]=sOutput[half+x];
    } else {
      sInput[i]=sOutput[x];
    }
  }
  cout << "Descrambled: " << sInput << endl;

  if (getche());
  return 0;
}
