Moved from C++ forum

[joker769]

hi, ive been searching for a sort of encrypter but more of a custom one... i need something that takes a file and reads every letter then creates a new file and writes the replaced text in it, like such...

the weather is good today
-read
-replace
-write new file
-new text write

(gaw ltrgatv bz pqqn gqkrm)

ive tried creating new parameters,
if (text == A || text == a)
{
newtext == r
}
but each time i try it it fails... all ive found is random password generators and algorithms i found no guides on this either, could someone please help.

So far ive found this... its close all id have to do is change the word to letter and do t one by one, but this is in c++ and i need c#... also in c# where would i put modified code?

 1.
      #include <stdio.h>
   2.
      #include <string.h>
   3.
       
   4.
      #define MAX_LEN_SINGLE_LINE 120 // ?
   5.
       
   6.
      int main()
   7.
      {
   8.
      const char fileOrig[32] = "myOriginalFile.txt";
   9.
      const char fileRepl[32] = "myReplacedFile.txt";
  10.
      const char text2find[80] = "lookforme";
  11.
      const char text2repl[80] = "REPLACE_WITH_THIS";
  12.
       
  13.
      char buffer[MAX_LEN_SINGLE_LINE+2];
  14.
      char *buff_ptr, *find_ptr;
  15.
      FILE *fp1, *fp2;
  16.
      size_t find_len = strlen(text2find);
  17.
       
  18.
      fp1 = fopen(fileOrig,"r");
  19.
      fp2 = fopen(fileRepl,"w");
  20.
       
  21.
      while(fgets(buffer,MAX_LEN_SINGLE_LINE+2,fp1))
  22.
      {
  23.
      buff_ptr = buffer;
  24.
      while ((find_ptr = strstr(buff_ptr,text2find)))
  25.
      {
  26.
      while(buff_ptr < find_ptr)
  27.
      fputc((int)*buff_ptr++,fp2);
  28.
       
  29.
      fputs(text2repl,fp2);
  30.
       
  31.
      buff_ptr += find_len;
  32.
      }
  33.
      fputs(buff_ptr,fp2);
  34.
      }
  35.
       
  36.
      fclose(fp2);
  37.
      fclose(fp1);
  38.
       
  39.
      return 0;
  40.
      }

Could you be more specific as to how it fails? eg, can you give us a simple example like:
The Day After
abcdefghijklmno pqrstuvwxyz
amfouxtwpdbznci skqhjeglvyr
jwu oay axjuq

which includes the translation index, and how it is failing (the wrong output)?
