compare

问题 I want to see if a variable is between a range of values, for example if x is between 20 and 30 return true. What's the quickest way to do this (with any C based language)? It can obviously be done with a for loop: function inRange(x, lowerbound, upperbound) { for(i = lowerbound; i < upperbound; i++) { if(x == i) return TRUE; else return FALSE; } } //in the program if(inRange(x, 20, 30)) //do stuff but it's awful tedious to do if(inRange(x, 20, 30)) is there simpler logic than this that doesn

问题 I am new to jmeter & I am looking for an option to compare two files using Jmeter. Both the files are generated using Save Response to file in jmeter. Also both files contain response to a jdbc request, with 100s of values across multiple columns & rows. I am using __FileToString() function in my response assertion to compare the two files. But this fails if my file has data with some special chars. Any tips how could I handle this ? OR any other ways to compare two Jmeter created files ? I

问题 I am stuck with a peculiar issue here. I have a script that basically imports a CSV file into a database using fgetcsv() in php. There is no problem in doing this at all and I am able to update old entries as well using MySQL syntax ON DUPLICATE KEY UPDATE (I am in no way a MySQL expert, hence me asking here). Here is that part of the code: $handle = fopen($file,"r"); fgetcsv($handle, 1000, ",");//skip first row since they are headers while(($fileop = fgetcsv($handle, 1000, ",")) !== false) /

问题 I want to compare select boxes selected option value, and if there are duplicate values in the select boxes I want to show alert: alert("Duplicate value!"); This is my code: <select class="examSelect"> <option value="one">ba</opion> <option value="two">woo</opion> <option value="three">coo</opion> <option value="four">po</opion> </select> <select class="examSelect"> <option value="one">ba</opion> <option value="two">woo</opion> <option value="three">coo</opion> <option value="four">po</opion>

问题 Today I've faced interesting problem of create test for pretty simple behavior: 'Most recent' sorting. All what test need to know: Every item have ID Previous ID is less then next in this case of sorting Approach : writing ID in to attribute of item, getting that id from first item with getAttribute() and either way for second. Problem : getAttribute() promise resulting with string value and Jasmine is not able to compare (from the box) string numbers. I would like to find elegant way to

问题 I have two JSON objects of the same structure - an original and one which I want to compare it to. There is only one level of information (i.e nothing has any children). I want to compare the two and remember which fields, if any, were different by storing the key in the secondDifferingFields ArrayList. def secondDifferingFields = new ArrayList() orignialJSON.each { print "original:"+it.value+":VS:"+secondJSON.it+":second" if (it.value != secondJSON.it){ secondDifferingFields.add(it) } } I

问题 Most of my small-scale project worked fine using dictionaries, so changing it now would basically mean starting over. Let's say I have two different dictionaries(dict1 and dict2). One being: {'the dog': 3, 'dog jumped': 4, 'jumped up': 1, 'up onto': 8, 'onto me': 13} Second one being: {'up': 12, 'dog': 22, 'jumped': 33} I want to find wherever the first word of the first dictionary is equal to the word of the second one. These 2 dictionaries don't have the same length, like in the example.

问题 == is not how we compare two arrays, since that would only compare the addresses: #include <iostream> int main() { char a[] = "aaa"; char b[] = "aaa"; if (a == b) std::cout << "Yes" << std::endl; else std::cout << "No" << std::endl; return 0; } This code even gives me a warning: Array comparison always evaluates to false But when I tried this: if ("aaa" == "aaa") It seemed to be working fine. Still gives me a warning, but the warning is: Condition is always true At first, I thought it was

问题 I have a simple data file. Each line in the file has four elements. Some lines are filled with no blank entries. Other lines have a first entry and the remaining three are blank, or rather "filled" with a space. It is a tab delimited file. Example of the input file: . . . 30 13387412 34.80391242 sSN_FIRST 30 13387412 34.80391242 sSN5_40 30.1 30.2 30.3 30.4 31 14740248 65.60590089 s32138223_44 31 14740248 65.60590089 s321382_LAST . . . To reiterate, the "blanks" in my file actually contain a
