c++ - Abnormal Output from program -

i have program should print out 2 lists 1 bellow, same list backwards, works first time prints weird output show bellow well.

0123456789 9876543210 

however actual output program this:

can tell me wrong code please, not sure why getting output.

void createfile(){   ofstream myfile;   myfile.open ("test1.txt");   for(int x = 0; x < 10; x++){    myfile << x << "\n";   }   myfile.close(); }  void poparray(int array1[]){   ifstream infile("test1.txt");    int x;   while(infile >> array1[x]){     cout << array1[x];   }  }  void reverselist(int array2[]){   for(int x = 9; x > -1; x--){     cout << setw(2) << array2[x];   } }   void checklists(int array1[], int array2[], int sizeofarray){   for(int x = array1[1]; x < sizeofarray; x++){     for(int y = array2[1]; x < sizeofarray; x++){         if(x == y)             cout << "palindrome" << endl;         else{             cout << "not" << endl;         }     }   }  }    int main() {   int array1[10];   int array2[10];    createfile();   poparray(array1);    cout << "\n";    reverselist(array1);    cout << "\n";   checklists(array1, array2, 10); } 

this problem think:

void poparray(int array1[]){  ifstream infile("test1.txt");   int x;  while(infile >> array1[x]){  cout << array1[x];  }  } 

you never specify x is. if understand you're trying think should work:

void poparray(int array1[]){  ifstream infile("test1.txt");   int x;  (x=0; x < 10; x++){   cout << array1[x];  }  } 

just read through bit more. you've got errors here:

void checklists(int array1[], int array2[], int sizeofarray){  for(int x = array1[1]; x < sizeofarray; x++){  for(int y = array2[1]; x < sizeofarray; x++){      if(x == y)         cout << "palindrome" << endl;      else{         cout << "not" << endl;     }     }    }  } 

i'd like:

bool checklists(int array1[], int array2[], int sizeofarray){  bool ispalindrome=true; for(int x = 0; x < sizeofarray; x++){      if(array1[x] != array2[sizeofarray-(x+1)]){         ispalindrome = false;         }  }  return ispalindrome; }   

then @ end of main have:

if(checklists(array1, array2, 10)){  cout << "is palindrome\n"; } else{ cout << "is not palindrome\n"; } 

while i'm @ might fix too:

void reverselist(int array2[]){ for(int x = 9; x > -1; x--){  cout << setw(2) << array2[x]; } }  

change to:

void reverselist(int array1[], int array2[]){ for(int = 0; < 10; i++){   array2[9-i] = array1[i]; } } 

i think if put bits of answer should more or less have works. i've not tested myself though.
