[ad_1] You need to declare myid as int before you pass it to int.TryParse int myid; string input = Console.ReadLine(); bool isString = int.TryParse(input, out myid); 0 [ad_2] solved int.TryParse failing with Console.ReadLine() in C#
[ad_1] if ( head->left ) temp = head->left; else temp = head->right; 0 [ad_2] solved C – Ternary operate to if else
[ad_1] Just put the cout outside the for loop, like this: for (size_t i = 0; i < boo.size(); i++) { while (boo[i] == ‘a’) { count+=i+1; if(count>b) b=count; // cout<<<<“a=”<<b<<“\n”;; //remove from here break; }} //add here cout<<<<“a=”<<b<<“\n”;; 1 [ad_2] solved Cout the last result only?
[ad_1] Here’s a recursive primality test function: int test_prime(unsigned n, unsigned d) { if (n < 2) { return 0; } if (d == 1) { return 1; } else { if (n % d == 0) { return 0; } else { return test_prime(n, d – 1); } } } Use it like: unsigned … Read more
[ad_1] If you use GCC for a compiler, you can use –save-temps which prevents the intermediate files (including the assembly output) from being deleted after it’s done. See http://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html [ad_2] solved assembler code of a fragment of C++ code [closed]
[ad_1] EDITED You must pass the instance of FrmA into the constructor of FrmMenu. In FrmA: private void Print() { FrmMenu ObjMain = new FrmMenu(this); ObjMain.Show(); } In FrmMenu: public FrmMenu(FrmA f2) { f2.CreateButtons(“NEW”); } 0 [ad_2] solved invoked function is not working in winforms [closed]
[ad_1] You could use GDI+ (and more specifically the Graphics class): // Load an existing image into a Graphics object using (var image = Image.FromFile(@”c:\work\input.png”)) using (var gfx = Graphics.FromImage(image)) { // Draw a line on this image from (0x0) to (50×50) gfx.DrawLine(new Pen(Color.Red), 0, 0, 50, 50); // save the resulting Graphics object to … Read more
[ad_1] You’ll get a divide by zero error if u <= 0 in: vidmerginu = ms / m; because m is set to 0 and not incremented. And a divide by zero error if u >= 0 in: vidvaikinu = fabs(vs / v); because v is set to 0 and not incremented. [ad_2] solved C++ … Read more
[ad_1] If you want to write the results in a file, move FILE *f = fopen(“test”, “w”); into your main() function (also check return value since the function can fail), if you want the file format to be csv then you should add the extension .csv so that other people know it has that format … Read more
[ad_1] This code int∗ p = &a[2]; is equivalent to this: int∗ p = a + 2; so even mathematically you can see that p – a is equal to a + 2 – a so I think result should be obvious that it is equal to 2. Note name of array can decay to … Read more
[ad_1] One simple solution would be to use a List instead of an array. List<string> temp = new List<string>(); It will need some tweaks but it will not limit you to 100 actions. In any other case, you should decide the strategy. Do you want to delete the initial items? Then remove your first X … Read more
[ad_1] crke[b] = ugib[b]; This line should be: crke[b] = ugib[z]; You might want to consider investing some time in learning how to use a debugger, which would’ve helped you figure it out. [ad_2] solved C++ Word guessing game [closed]
[ad_1] You set array[i] to i if i is a prime number. But you do not set array[i] to any value if i is not a prime number. You probably only want to store the prime numbers in array, so void fillArray(int array[], const int N){ for (int i = 2, j = 0; j … Read more
[ad_1] var today = DateTime.Now; var nextFriday = today.AddDays(DayOfWeek.Friday – today.DayOfWeek).Date; You can get the next friday which is the last day of the week as in your question 0 [ad_2] solved How to get last date of the current week based on current date in C#
[ad_1] This is not pure C++. It looks like somebody has written either a compiler extension or a series of macros to allow the specification of pre- and post-conditions for a block of code. You’re going to have to ask that person. (As an aside, this is why just “extracting code” is often insufficient for … Read more
