String Problems

2 New Member
Reading numbers from file into two strings, converting to int using atoi so I can use addition. Now I need to convert back to strings. I can't find a way to converting the ints that I just created using atoi in to a string format! Any help would be great.

Sorry, additional info: the string I need has to be written out to a new file. using the g++ compiler

  1. int x = 45;
  2. char myString[50];
  3.  
  4. sprintf( myString, "%d", x );
  5.  
  6. /* or if you are using a file handle */
  7.  
  8. FILE *fout;
  9.  
  10. fout = fopen( "MyFile.txt", "w" );
  11.  
  12. if ( NULL != fout )
  13. {
  14.     fprintf( fout, "%d\n", x );
  15.  
  16.     fclose(fout);
  17. }
  18.  
Obviously sprintf and fprintf can take all the format strings that you could pass printf.
