I have declared following function prototype to work with myArray . void first ( int n , short ar [][ 30 ]); void second ( int n , short ar [ 30 ]); void third ( int n , short (* ar )[ 30 ]); My understanding is that the ar parameter in both first and third function are equivalent. short ar[][30] in first function is equivalent to the short (*ar)[30] in third function because they are both pointer to array of 30

This is what I have so far: jQuery('#colCenterAddress').val(function(i,val) { var f = ['Rd','St','Ave']; var r = ['Road','Street','Avenue']; return val.replace(f,r); }); Thoughts? 回答1: You need to iterate the f Array, and try each replace separately. jQuery('#colCenterAddress').val(function(i,val) { var f = ['Rd','St','Ave']; var r = ['Road','Street','Avenue']; $.each(f,function(i,v) { val = val.replace(new RegExp('\\b' + v + '\\b', 'g'),r[i])

I want to read the file line by line and append each line to the end of the list. 回答1: with open(fname) as f: content = f.readlines() # you may also want to remove whitespace characters like `\n` at the end of each line content = [x.strip() for x in content] I'm guessing that you meant list and not array. 回答2: See Input and Ouput : with open('filename') as f: lines = f.readlines() or with stripping the newline character: lines = [line.rstrip('\n') for

For example: function test(){ var a = Array.prototype.slice, b = a.call(arguments); // Do something setTimeout(function(){ var c = a.call(arguments); // Do something else }, 200); } So instead of calling Array.prototype.slice.call(arguments) , I can just do a.call(arguments); . I was trying to make this even smaller by caching Array.prototype.slice.call , but that wasn't working. function test(){ var a = Array.prototype.slice.call, b = a(arguments); // Do something

Is there a NumPy or Python routine dedicated for this task? Or, do I need to iterate over the elements in my script? 回答1: You have multiple options. Two options are the following. numpy.sum(boolarr) numpy.count_nonzero(boolarr) Here's an example: >>> import numpy as np >>> boolarr = np.array([[0, 0, 1], [1, 0, 1], [1, 0, 1]], dtype=np.bool) >>> boolarr array([[False, False, True], [ True, False, True], [ True, False, True]], dtype
