  You shouldn't use the ___ to maintain indents.
  
  Just push the C button above, and THEN paste your code.
  

  [ code ]
  
  This is code
  
  [ /code ]
  
  

  
  normally there are no spaces in the code tag, but I had to add them, like JohnnyMac shows below.
  
  You can edit your first post and put the code inside the code tags.

  I don't write a lot of C but seem to remember encountering this when writing the PixyCam library. I found this function that declares the loop variable outside the loop, though I would normally do as you're doing.
  

  void showColorCodes()
  {
    int32_t nccodes;
    uint8_t i;
    
    nccodes = pixy2_getBlocks(CC_MAP, MAX_BLOCKS);
    
    if (nccodes < RESULT_OK)  
      showError(nccodes);
    else {
      print("%d color codes detected\n\n", nccodes);
      if (nccodes > 0) {
        for (i = 0; i < nccodes; i++) {
          pixy2_extractBlock(i, &b.signature);
          // printf required for octal
          printf("ccode: %3o  x: %3d  y: %3d  ", b.signature, b.xpos, b.ypos);
          printf("w: %3d  h: %3d  a: %+3d\n", b.width, b.height, b.angle);
        }
        print("\n");
      }
    }    
  }
  

  BTW... If you click on C on the forum entry toolbar you'll get code tags that will make reading your code easy without you having to insert padding. Copy and paste your code between the [ code ] and [ /code ] tags.

  #include "simpletools.h"                      // Include simple tools
  char text[16];
  char pass[7] = {"abc 123"};
  
  int main()                                    // Main function
  {
      print("Enter Password: ");
      for(int i = 0; i < 16; ++i )
      {
          text[i] = getChar();
          putChar('*') 
          if(text[i] == '\r' || text[i] == '\n')
            {
                putChar('\n');
                text[i] = 0;
                break;
             }
       }                    
    
    if(!strcmp(pass, text))
    {
      print("(pass does match text)\n");
    }
    else
    {
      print("(pass word does NOT match text)\n");
    }          
   
  }
  
  

  
  
  OK

  Swing and a miss! -- you have to paste your code between the tags.

  There's a semicolon at the end of your for statement:

  for(int i = 0; i < 16; ++i );
  

  Remove the semicolon and see what happens.

  Also

  putChar('*')
  

  
  Needs a semicolon.
  

  putChar('*');
