Thread: I need some solution for linked list and file

I have the exercise about linked list and file, so can you help me or give me some solution

Code:

 Print the result to the output file named: output.txt 
a)  First line: two numbers (separated by a white space). First number is the sum of all 
nodes, which have positive values. Second number is the position of the node, which 
has the maximum value (as described in the #2.f above).  
b)  Second line: Nodes inside the list before it is sorted. Each is separated by a white 
space. 
c)  Third line: Nodes inside the list after it is sorted. Each is separated by a white space. 
 
For example: 
 
Input.txt 
6 2 4 3 
-2 4 1 -3 7 6 
 
Output.txt  
22 4 
-2 4 1 4 7 6 
-2 1 4 4 6 7

What have you written or tried so far?
