#include <stdio>
#include <string>
#include <fstream>
using namespace std;
int main()
{
FILE * pFile;
char mystring [100];
char tmp[100];
unsigned int x;
int numchars = 60;
int string_length;
//read from file.
pFile = fopen ("input.txt" , "r");
if (pFile == NULL) perror ("Error opening file");
else {
fgets (mystring , 100 , pFile);
puts (mystring);
fclose (pFile);
}

//Measure the length of the string.
string_length = strlen(mystring);

//Output the last characters of the string.
for(x=36;x<string_length;x++)
{
if (x<=numchars)
cout << mystring[x];
}
return 0;

} [/quote]

FILE * pFile;
char mystring [100];
int string_length;

ofstream output;

pFile = fopen ("input.txt" , "r");
output.open("output.txt", ios:: out);


fgets (mystring , 100 , pFile);
puts (mystring);

string_length = strlen(mystring);

int i=36;

while (i < 60)
{
output<<mystring[i];
++i;
}


fclose (pFile);
output.close();
return 0;

apsal ko suka sangat tekan enter banyak kali ni? susah betul aku nak faham soalan ko.
benda yg ko nak tu di panggil Inter process communication (IPC), banyak teknik boleh digunakan seperti file, pipe, etc. pada pendapat aku, file la paling senang nak difahami.

aku x brp paham apa yg ko nak sbnrnya.

yg aku paham ada satu fail input.txt yg contain dlm fail tu ialah "26/01/10 09:20:20 MAL BIN BIN275 TSTCB U8L5 O/CR ..N UCOS Operated".

pastu berdasarkan kod yg latest ko post tu fail output.txt yg keluar ialah "BIN275 TSTCB U8L5 O/CR".

tp bila aku compile yg keluar hanya "CB U8L5 O/CR ..N UCOS Op".

kat sini aku dah start pening.mn satu yg betul sbnrnya.

yg sbnrya ko nak keluarkan "O/CR" sahaja atau "BIN275 TSTCB U8L5 O/CR".

tlng jelaskan aku yerk...
