[ad_1] I am create a simple project for you look image for sample code. Add a timer for update values.And click timer one time set start with application true And add two label.(Sample: label1 is progressbar value / label 2 is progressbar max. value) And add a button for set progressbar max value. Code sample: … Read more
[ad_1] How to print digits in ascending order from 1 to n using recursion ,where n is given in the parameter of that function [closed] [ad_2] solved How to print digits in ascending order from 1 to n using recursion ,where n is given in the parameter of that function [closed]
[ad_1] Since Time is a struct all the fields need to be initialized in the constructor. Change your first two constructors to the following: public Time(int s1) { s = s1; m = h = 0; } public Time(int s1, int m1) { s = s1; m = m1; h = 0; } or even … Read more
[ad_1] ! means not. IsNullOrWhiteSpace is a static method of String which returns a boolean value, so the code is returning whether both ‘Code’ and ‘State’ have a value. [ad_2] solved What does this “!string” mean?
[ad_1] printf without arguments is the function pointer, worth a non-zero value (it’s built-in so the pointer cannot be zero) Now you apply logical negation (!) on this non-zero value: you get zero. Now negate this zero bit-wise (using bit to bit negation ~), you get all 1s in the int bit range (which can … Read more
[ad_1] Is this Correct? No. Mixing new and malloc() is not a good idea. If you must use dynamic memory allocation, then read this: How do I declare a 2d array in C++ using new? Otherwise, use an std::vector. 12 [ad_2] solved c++ : An array of the pointer float type with dynamic size
[ad_1] Here’s a pretty straight forward recursive implementation. Sadly, it’s not tail recursive though. Full Implementation: char *rfind(char* str, char ch) { if (*str == ‘\0’) return NULL; char * pos = rfind(str + 1, ch); if (pos != NULL) return pos; if (*str == ch) return str; return NULL; } Base Case: str is … Read more
[ad_1] you declared the function: int blit_image(char chemin[15],SDL_Surface *fenetre,int posx,int posy) { So that that parameter #1 has 15 characters. But when you call it, you call it with: blit_image(“resources/images/fondblanc.bmp”,fenetre,0,0); That filename is 31-characters by my counting, and will not fit into 15 characters. I also added some printf-statements to your code which will help … Read more

[ad_1] I would be doing you a disservice to give you “code for logging”, but I can point you towards the File class, which contains useful methods for writing text to a file. Since you specify no other needs, I suspect it will suffice. File http://msdn.microsoft.com/en-us/library/system.io.file.aspx [ad_2] solved How to create a log file in … Read more
[ad_1] The problem is in foreach templated function: first parameter can be a pointer to the array or it can just be static array array with undefined size second parameter can be a function pointer or a reference to the function (which should accept constant element of same type as array elements by reference, as … Read more
[ad_1] You made a couple of mistakes #include <math.h> #include <iostream> using namespace std; int main() { char ch1, ch2; for (int i=i; i<=20; i++) { int a = rand () % 20; cout << “The number is: ” << a << endl; ch2 = ‘y’; //You only need to loop until its square root; … Read more
[ad_1] There is a popular math theorem – Fermat’s Great (Last) Theorem – that states for any integer n > 2 there does not exist non-zero integers a, b, c such that a^n + b^n = c^n. 2 [ad_2] solved consider x^i+y^i=z^i, x
[ad_1] EDIT: Since according to the OP, the code is in a function, and score is defined, this is more than likely a case of the computer being a jerk. Restart should theoretically solve the problem. The code’s logic is correct as it stands. Syntactically, there are two major problems: it must be in a … Read more
[ad_1] Here shows you how to use regex in C#. You could always just loop the directory that you’re looking in and check the file names instead of making a regex. (You’ll need to use System.IO) Perhaps something like this? string [] fileEntries = Directory.GetFiles(targetDirectory); Regex regex = new Regex(“target file name”); Match match = … Read more
