C++ File

Hi, I have one text file which stores the hex values in different lines(APDU.txt). Eg; 02 01 00 BE 10 04 0E 08 00 06 10 00 2B 61 29 A1 09 06 07 And I need to process this line by line. Here is a sample code that m used so far; FILE *myFile = fopen("D:\\APDU.txt", "rb"); BYTE *buffer,*buffer1; int lengthFile=0; char temp[3]; if(myFile!=NULL) { fseek(myFile,0,SEEK_END); lengthFile=ftell(myFile); fseek(myFile,0,SEEK_SET); buffer=new BYTE[lengthFile+1]; memset(buffer,0,lengthFile+1); fread(buffer,sizeof(BYTE),lengthFile,myFile); fclose(myFile); } buffer1=new BYTE[lengthFile/2]; memset(buffer1,0,lengthFile/2); memset(temp,0,sizeof(temp)); for(int i=0,j=0;i

Do you have some sort of a question?
Why is common sense not common? Never argue with an idiot. They will drag you down to their level where they are an expert. Sometimes it takes a lot of work to be lazy Please stand in front of my pistol, smile and wait for the flash - JSOP 2012

are you giving us the code ..... or you forgot the question

Since
bufferhas not been properly initialized, what are you expecting this to do?Member 8747425 wrote:
