[Solved] Make a new pointer in a loop C

by

[ad_1] i and id are both local variables with automatic storage (commonly referred to as on the stack). No new instances are created upon each iteration of the loop, the same space is reused and a new value is stored in id, hence the same addresses printed by printf. Note that the value of id … Read more

[Solved] istringstream to int8_t produce unexpected result

by

[ad_1] The problem is int8_t is implemented as char. The implementation of the input stream is working like this: char x; std::string inputString = “abc”; std::istringstream is(inputString); is >> x; std::cout << x; The result is ‘a’, because for char the input stream is read char for char. To solve the problem, provide a specialised … Read more

[Solved] Program crashes when a function returns empty

by

[ad_1] The main problem I see with your code is the reading loop, it has mainly two issues Read: Why is while (!feof(rPtr)) always wrong. You must check the return value of scanf(), and prevent scanf()‘s from overflowing the destination buffer, so the loop condition should be while (fscanf(rPtr, “%14s%lf%lf%lf”, fromDb.name, &fromDb.dArea, &fromDb.dLength, &fromDb.dFormFactor) == … Read more

[Solved] Sum of multiples of two numbers

[ad_1] Try this code: a = input(“enter first number\n”) b= input(“enter second number\n”) limit=[] limit.append(a) limit.append(b) natNo=range(1,1000) xyz = [] for i in limit: xyz +=filter(lambda x: x == i or x % i==0, natNo) set = {} map(set.__setitem__, xyz, []) nums=set.keys() print “the multiples of the given numbers are: “+str(nums) c=reduce(lambda x, y:x+y, nums) … Read more

[Solved] WPF creating grid from XAML in code-behind

by

[ad_1] You can do that by making your “existing grid” a separate UserControl. First, you need to add a UserControl via [Add]->[User Control…]->[User Control (WPF)]. Next, put your “existing grid” inside the added UserControl. YourExistingGridControl.xaml <UserControl x:Class=”Your.Namespace.YourExistingGridControl”> <Grid> … YOUR EMPTY GRID WITH ALL THE COLUMNS, ETC. … </Grid> </UserControl> Now, you can create as … Read more

by

[ad_1] In your: if ( buff == ‘\n’ && fe && fn ) //<– I assume you want to check if an empty line was read by checking it against the newline character. However, buff is not the character; it is a pointer to were all the characters read are stored. To check if the … Read more

[Solved] perl grep with / on array

[ad_1] Perhaps the following will be helpful: use strict; use warnings; print “Interface Name,Vlan Id,IP Address\n”; while (<DATA>) { my $interface = /interfaces\s+(\S+)\s+/ ? $1 : q/”/; my $vlanID = /unit\s+(\S+)\s+/ ? $1 : q/”/; my $ip = /address\s+(\S+)\s+/ ? $1 : q/”/; print “$interface,$vlanID,$ip\n”; } __DATA__ set interfaces ge-1/0/0 unit 0 family inet address … Read more

[Solved] Multiple line plots sharing abscissas axis in gonum/plot

by

[ad_1] Yes, it is possible. You can use plot.Align: package main import ( “math/rand” “os” “gonum.org/v1/plot” “gonum.org/v1/plot/plotter” “gonum.org/v1/plot/vg” “gonum.org/v1/plot/vg/draw” “gonum.org/v1/plot/vg/vgimg” ) func main() { rand.Seed(int64(0)) const rows, cols = 2, 1 plots := make([][]*plot.Plot, rows) for j := 0; j < rows; j++ { plots[j] = make([]*plot.Plot, cols) for i := 0; i < cols; … Read more

[Solved] C++: Using remove_if to filter vector on a condition

by

[ad_1] Below example demonstrates the usage of erase-remove_if. limit is captured by reference and can thus be modified outside the lambda: #include <vector> #include <algorithm> #include <iostream> int main() { std::vector<int> vec{0,1,2,3,4,5,6,7,8,9}; int size = vec.size(); for (int limit = 0; limit <= size; limit++) { vec.erase(std::remove_if(std::begin(vec), std::end(vec), [&limit](int i) { return i < limit; … Read more

[Solved] Python – Read string from log file

by

[ad_1] Can be extracted with a simple regular expression, as long as the text file is in the same format as the Python log output you posted (Returns all of them): import re file=””.join([i for i in open(“yourfileinthesamefolder.txt”)]) serials=re.findall(“u’serial_number’: u'(.+)'”,file) print(serials) I suggest reading up on how to use regular expressions in Python: Regular Expression … Read more

[Solved] Sort Multi-Dimensional Array PHP

by

[ad_1] If I understand what you need to do, you can use usort: usort($array, function($a, $b) { $sort = array(‘Red’, ‘Green’, ‘Blue’); if (array_search($a[‘House_Colour’], $sort) > array_search($b[‘House_Colour’], $sort)) return 1; if (array_search($a[‘House_Colour’], $sort) < array_search($b[‘House_Colour’], $sort)) return -1; return 0; }); If you can leverage on defines instead on relying on strings for the house … Read more
