[royal1]

Hi ,

I am reading string array from one txt file and now i want to compare the first character of the each element of this array and read corresponding line.How can i do it?i have attached some picture so you can understand easily.

Thanks for reply

You did not get my question actually in above picture you can see first character is like

0                           o.4755  21

0                           0.4766  22

1                           0,4822  36

1                           0,4877  23

This is my index for measurement.now for another measurement i want to read this first character(index no) and select corresponding row

0

0

1

1

this first character itself is index number for my measurement so i want to search this index no and read corresponding line like here i want measured value for no 1

Are you trying to read all of the lines with an index of 1?  If not, which one do you read?

[royal1]

yes exactly i need all line with character 1(index 1)

Hi, I guess u are looking for multiple search result as shown.

If not replace for loop with while loop with "stop"  criterion either "i => array size" or search criteria gets any match

Yes my friend exactly i want this one

Thank you very much
