12.05 Mac 00.00 Mac
1.25 Joa 1.25 Joa
5.55 J9 5.55 J9

I am tring to read the above file from the start to end and convert the time to 24 hour time as shown on the right and save the text file with the converted time.
Heres what i have coded so far.

// Program to open .txt file covert and save to new name.

#include <stdio.h>

void main( void )
{
FILE *fp; // file pointer

float *time; // store original time
int nTimeFlag=0; // time flag
float nTmpTime=0.00; // ref time.

char buffer[900]; // store in read data
int i, ch;
/* Open file for reading (fail if data does not exist) */
if( (fp = fopen( "test.txt", "rt" )) == NULL )
printf( "error opening file \n" );
else
printf( "file opened \n" );
/* Read in characters and place them in "buffer": */
ch = fgetc( fp);
for( i=0; (i < 899 ) && ( feof(fp ) == 0 ); i++ )
{
// store original time in array time

buffer = (char)ch;
*time = buffer;
if (*time < nTmpTime)
{
if (!nTimeFlag)nTimeFlag=1;
else nTimeFlag =0;
}
buffer=*time;
if (nTimeFlag)*time +=12.00;
buffer =*time;
ch = fgetc( fp );
}

printf( "%s\n",buffer);

fclose(fp);

}

Can some one pls help me, or put me in the right direction, i can not get the time cinversion side working.

Thanks!!.
