问题 I'm very new to C and I'm trying to write a program that checks if a string contains any uppercase letters, and if it does, prints them out. I'm using https://www.onlinegdb.com/online_c_compiler# as my compiler (cause I don't have access to my personal computer right now) and after a test run, the results are (p.s. I know gets isn't safe): main.c:16:5: warning: ‘gets’ is deprecated [-Wdeprecated-declarations] /usr/include/stdio.h:638:14: note: declared here main.c:(.text+0x26): warning: the

问题 Really struggling with double quotes, double percent signs etc in batch script. So i have a folder, lets call it C:\EncryptedFiles It can have one or more subfolders, and each subfolder can have one or more encrypted file (with extension gpg). I need to look at everything inside C:\EncyptedFiles folder and iterate over files in each subfolder, and decrypt those files in same place where encrypted file is there. So if we have another folder called Subfolder1 with file EncryptedFile1.csv.gpg,

问题 I have a matrix u , I want to go across all rows and all columns and do the following. If the element is non zero, I return the value of the row index. If the element is zero, find the row index the next non zero element after this element. I can do this easily using two for loops with a find function. But I need to do this many many times (not because of the size of the matrix but because this is called many times). How can I do it faster? here is the for loop code: for w=scenario_size:-1:1

问题 I'm making a water simulation program, and I need it to do a for loop through y, x. But I need it to check the most bottom y first, then up. This is my lvl: lvl = [[0, 0, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0]] I need it to check lvl[4] and then lvl[3], lvl[2], etc. Please help! NB: I'm using nested for loops, so I can check y, x. 回答1: You can use the reversed built-in method to reverse the ordering of your list of lists: for li in reversed(lvl): print li

问题 This question already has answers here : php variable scope (6 answers) Closed 5 years ago . I'm new in PHP, I don't understand why the final result of the code below is '233' instead of '231', isn't the $a in foreach is a temp variable? <?php $a = '1'; $c = array('2', '3'); foreach($c as $a){ echo $a ; } echo $a; ?> Can anyone help? Thks. Updated 2014-11-28 Now I know what was my problem. As the accepted answer and this answer have pointed out, neither the foreach nor the while act like
