Reading integers from a text file

Question

I have a text file, in which I am writing 3 things

Eg < int,int,char> for each word.

Now, I am reading the file such that I consider a block of 3.1st one I always consider an integer, 2nd one also as integer and the 3rd one as character .There is no problem when the integer is from 0-9 but when it exceeds like 10,100 then my program doesn't work for the obvious reasons.

Like there is no problem when I have to read this

11a     here <1=int,1=int,a=char>

but when something like this comes, I face problem

152a    here <15=int,2=int,a=char>

I have put the whole text file in a string.Now, how how do I read the characters that I no longer face the above mentioned problem

Some more info: My text file contains characters like this
11a22d33f1234f

Answer 1

Given your current description of the problem, there is no way to determine if an entry such as

152a

corresponds to (15,2,a) or (1,52,a) .

Why don't you write to the file with some delimiter between elements, and then split() around the delimiter when reading back in from the file?

Answer 2

您的文本文件格式不正确，那么您想如何区分“ 1 11 a”和“ 11 1 a”？例如，您不能使用csv或类似的东西吗？
