Line number is known, the number of columns is unknown,

For example:
12.03, 515.04, 117.9, 52.79, 13.58
18.03, 415.04, 217.9, 42.79, 23.58
11.03, 315.04, 317.9, 32.79, 33.58
1.03, 215.04, 417.9, 22.79, 43.58
32.03, 115.04, 517.9, 12.79, 53.58

Can't do
How many columns must be explicitly
Rows can not directly determine instead

The most simple way to find a CSV library

Part of the code to borrow 3 floor save trouble, just reply to a reading of the text, modified directly, even don't know any ranks it doesn't matter, is behind the data should have a comma,

CodePudding user response:

Reply didn't notice the request is quite good, existing in a two-dimensional array
Now save the data string and the two-dimensional array has nothing to do
If only read the data output
That's too simple

reference 5 floor wise men know already should good karma response:
