Solution 1

well, if new line is the indicator of your one line, then count 10 new line, when you would reach the 10th new line you will start storing in your next array.

Solution 2

Hi there,

use getline api and read the each line from the file and maintain the count to read the lines from file.
if counts reach 10 means stop adding into first CStringArray. If the count starts 11, so start adding into another CString Array.

like wise you can split.

regards
Ranjith

but still i used getline function inside a for loop: and can i use if statement to check the incriment and give anothe array? eg: if(a > 11 && a < 22)

for example:
declare int count variable in global;
open the file
if(file Handle != NULL)
do
{
read the line from file
add lines into CString array
count++;

if(count == 11)
add the lines(data) into another array
else if(count == 21)
add the lines(data) into another array
else if(count == 31)
add the lines(data) into another array
else
add the lines(data) into another array.

}while(fileHandle != EOF)

You may try this method....

while( !lo.eof())
{
getline(lo,arr1[i]);

if( i == 11)
{
getline(lo,arr2[i]);
}

else if( i == 22)
{
getline(lo,arr3[i]);
}

else if( i == 33)
{
getline(lo,arr4[i]);
}

else if( i == 44)
{
getline(lo,arr5[i]);
}

else if( i == 55)
{
getline(lo,arr6[i]);
}

else if( i == 66)
{
getline(lo,arr7[i]);
}
i++;
}

this thing doesnt work :/ any idea?
