Your desired output changes every time you add a new post to this thread.

I suggested code in post #11 that gets rid of the need to need for the for loop you showed us in post #12 and produces the results that loop would produce inside the print_total() function.

The code that I suggested there worked perfectly with the earlier sample data you provided to produce the output you said you wanted in an earlier post in this thread. If you modified that code to produce a different output format and introduced a syntax error in the code as you did it, I can't help you without seeing how you modified the code. Since your requirements are constantly changing and since you haven't provided us with any sample input that could possibly produce the most recent output you're showing us, I'm not motivated to try to rewrite my suggestion again hoping to guess at what your next output format requirements might be.

AFINITSAMPLEFORMAT(3)													     AFINITSAMPLEFORMAT(3)

NAME

       afInitSampleFormat, afInitByteOrder, afInitChannels, afInitRate - initialize audio data format for a track in an audio file setup

SYNOPSIS

       #include <audiofile.h>

       void afInitSampleFormat(AFfilesetup setup, int track, int sampleFormat,
	   int sampleWidth);
       void afInitByteOrder(AFfilesetup setup, int track, int byteOrder);
       void afInitChannels(AFfilesetup setup, int track, int channels);
       void afInitRate(AFfilesetup setup, int track, double rate);

PARAMETERS

       setup is a valid file setup returned by afNewFileSetup(3).

       track specifies a track within the audio file setup. track is always AF_DEFAULT_TRACK for all currently supported file formats.

       sampleFormat is a symbolic constant specifying the sample format for the audio data in the track. sampleFormat must be one of
       AF_SAMPFMT_TWOSCOMP, AF_SAMPFMT_UNSIGNED, AF_SAMPFMT_FLOAT, or AF_SAMPFMT_DOUBLE.

       sampleWidth is a positive integer specifying the number of bits for each sample in the track.

       byteOrder is a symbolic constant specifying the byte order of the track. byteOrder must be one of AF_BYTEORDER_BIGENDIAN or
       AF_BYTEORDER_LITTLEENDIAN.

       channels is a positive integer specifying the number of channels in the track.

       rate is a positive double-precision floating-point number specifying the sample rate of the track.

DESCRIPTION

       afInitSampleFormat initializes the track to the specified sample format and sample width.

       afInitByteOrder initializes the track to the specified byte order.

       afInitChannels initializes the track to the specified number of channels.

       afInitRate initializes the track to the specified sample rate.

ERRORS

       afInitSampleFormat, afInitByteOrder, afInitChannels, and afInitRate can produce the following errors:

       AF_BAD_FILESETUP   setup represents an invalid file setup.

       AF_BAD_TRACK	  track represents an invalid track identifier.

       afInitSampleFormat can also produce the following errors:

       AF_BAD_SAMPFMT	sampleFormat does not represent a valid sample
			format.

       AF_BAD_WIDTH	sampleWidth is not a valid sample width.

       afInitByteOrder can also produce the following error:

       AF_BAD_BYTEORDER   byteOrder does not represent a valid byte order.

       afInitChannels can also produce the following error:

       AF_BAD_CHANNELS	 channels specifies an invalid number of channels.

       afInitRate can also produce the following error:

       AF_BAD_RATE   rate specifies an invalid sample rate.
