c++ - How to go from absolute path to relative path? -


I am making a small program to help in reading the file.

I have to take command from a command line in: 

 for  (i = 1; argc> i; i ++) {QString path = QDir:: Current Path () + "/" + Caststring (argv [i]); QDir dir (path); FileSearch (dir); }   
 From there, I say another method where I look at each file / folder and get the size and its file or folder.  
  Zero file search (QDir dir) {foreach (QFileInfo info, dir.entryInfoList (QDir :: NoDotAndDotDot | QDir :: Files | QDir :: AllDirs)) {if (info.isFile )) {QDebug () & lt; & Lt; Info.path () & lt; & Lt; "There is a file! Its size is:" & lt; & Lt; Info.size () & lt; & Lt; Endl; } If (info.isDir ()) {qDebug () & lt; & Lt; Info.path () & lt; & Lt; "There is a directory! Its size is:" & lt; & Lt; Info.size () & lt; & Lt; Endl; FileSearch (info.filePath ()); }}   
 Rather than reading the entire path, I want to read only the relative path. So instead of reading it:  
  Home / John / Desktop / Project / Current Project / Check Directory is a directory! Its size is: 4096 Home / John / Desktop / Project / Current Project / Check Directory / test.txt is a file! Its size is: 4   
 I have to read this:  
  is a check directory / a directory! Its size is: 4096 checkdirectory / test.txt is a file! Its size is: 4  
 
 postprop Amp;; file name);   
 The relative file path should be returned.

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
