Urgent Strings help!!!
 |
hi there.
i have 6 long numbers in a text file that i am reading from.
these numbers can be of any length but written in the one of the formats as i have written below.
the numbers are
102,2131,432 //format 1
32,531 //format1
74 //format2
534532.5 //format3
1,500 //format1
3,120,352 //format1
i want the output as
102
32
74
534532
1
3
. i.e. the numbers before the commas or the dots. i want to discard everything else. Any idea how i can get them???
i have the code to read the file and stuff. i just need the code for this bit.
the output is inside the same while loop that i am using to read the file. the loop is...
while(fscanf(MYFILE,"%s", &STOREHERE) == 1)
{
//my code is here
}
i dont want to put my code here because its a very long and complicated one. n i dont want to confuse all of u by telling u d whole thing. please help me in getting just what i have stated above.
Many thanks in advance,
Tim.

as far as i know, the isdigit function will not work for a large number including commas.
for xample, a number like 43,123,321 wont be handled by the function
