It’s your so-called bubbleSort that’s actually not at all an implementation of bubble sort that fills your array with the same number, in a convoluted way. (How could it possibly be a sort function if it doesn’t ever compare values of the array?) Why don’t you use the C standard library qsort function if you … Read more
From VS menu bar you can select Project -> Project properties(on the bottom) and then go to Resources tab. From here, you can add the resource(s) from disk, by hand. Then you can access them from code like this: PictureBox pb = new PictureBox(); pb.Image = Properties.Resources.NameOfResource; Don’t forget to set the rest of PictureBox … Read more
I don’t use SQL Express very often, but it looks like your connection string is not right. In your screenshot 1 it shows DESKTOP-VN2SRQQ\SQLEXPRESS as your SQL server\instance. In screenshot 2 you have chosen (localdb)\mssqllocaldb as the server\instance. Try changing the server to DESKTOP-VN2SRQQ\SQLEXPRESS 0 solved I didn’t found the database in Entity Data Model … Read more
A simple approach is using string.Split() to split the words by white-space, take two words via Enumerable.Take and then join them with white-spaces again: string firstTwoWords = string.Join(” “, text.Split().Take(2)); Remember to add using System.Linq; Demo solved How can I substring word in C#
You need to define a flag which will be set after the first find. void delete (int s[] , int &top , int v) { bool found = false; int ts[size] ; int ttop=-1; while(top!=-1) { if (s[top]!=v) { push(ts,ttop,s[top]); } else { if (found == false) { found = true; push(ts,ttop,s[top]); } } pop(top); … Read more
See it yourself : void LoginScreen(){ //you still want to use addUser from main, so what is this ? UserInfo addUser[100]; ———–+ … | } | | void main() | { | | UserInfo addUser[100]; ————+ … } You can do something like this : void LoginScreen(UserInfo addUser[] ){ … } Obviously you need to … Read more
The error is that %d in the format specifier of both scanf and printf represents decimal, so it expects an int (in the case of scanf, a pointer to int) Since you are declaring b and c as float, %d in the lines scanf(“%d”,&b); printf(“%d lbs is %d kgs.”,b,c); should be changed to %f respectively. … Read more
And please no win32, mfc or qt. I fear these are too complex for me for now, unless you really recommend it. Doing graphics without some kind of framework is actually a lot harder than using any one of the frameworks that you have listed. Orders of magnitude harder … if you could measure hardness … Read more

This seams to be bad quality code! Maybe not dangerous, as const appears in prototype. myFunc(const void * p) accepts a pointer to anything and const should mean it won’t touch it. Now, st is a pointer to myStruct, so st->arr is the value of arr member and &st->arr is memory address of arr member. … Read more
The operator new[] allocates size bytes of storage, suitably aligned to represent any object of that size, and returns a pointer to the first byte of this block. realloc changes the size of the memory block pointed to by ptr. In your case, the first call on new[] operator creates a block, and then stores … Read more

Get yourself and enum with the values. Easier to handle than strings. public enum Vals { IF, THEN, ENDIF, ELSE, } We have a method for comparing if the next value is correct pair with the current. public static bool IsValidFollower(Vals val1, Vals val2) { if (val1 == Vals.IF) return val2 == Vals.THEN; if (val1 … Read more
