[Solved] length of a character pointer not correct using strlen()

by

The argument a (a pointer) is passed to input() by value. So the change a = regrowchar(a, size) is not visible to main(). Pass it by reference. Also, although you haven’t asked, your code leaks memory, since it dynamically allocates but never deallocates. by https://stackoverflow.com/users/4706785/peter 2 solved length of a character pointer not correct using … Read more

[Solved] Streamreading text files

by

You are mistaken to think it is reading the first line. In fact, your current code reads the first value of each line. Due to your input this just happens to be a similar output to what the first line would be, which has lead to your confusion. Your main loop should be looping through … Read more

[Solved] error: invalid use of incomplete type ‘class Theron::EndPoint’ [closed]

by

Your include statements are wrong, or in the wrong order. Apparently Theron/Framework.h contains some code that needs the full definition of class EndPoint but doesn’t explicitly include the header EndPoint.h and instead only provides a forward declaration. To fix this, you can either try to include EndPoint.h before including Framework.h or replace all your Theron … Read more

[Solved] Why does int seem to default to 50 rather than 0 in C#?

by

It’s not printing 50 more times; it’s printing exactly 48 more times. You’re reading a character and assigning its unicode value to an integer. For example, user types ‘1’, the character 1. Its Unicode value is 49. You assign 49 to your int print, and there you are. A character is really a small or … Read more

Use typedefs to help: #include <stdio.h> typedef char (*functionPtr)(void); typedef char (**arrayOfFunctionPtr)(void); // OR THIS // typedef functionPtr* arrayOfFunctionPtr; typedef arrayOfFunctionPtr (*functionReturningArrayOfFunctionPointers)(void); int main() { functionReturningArrayOfFunctionPointers f; char s() { return ‘y’; } char (*g[1])(); g[0] = s; printf(“%c\n”,g[0]()); arrayOfFunctionPtr func() { return g; } f = func; printf(“%c\n”,(f())[0]()); return 0; } solved Error while … Read more

[Solved] I need an algorithm to concatenate 2 vectors and also update the vector in cases of common element in C++ (not specific to C++11) [closed]

by

The most simple approach would be to just check for every element in src vector, if an duplicate exists in dest vector or not. If it exists just append Duplicate to it, else you can just push back the element as a new element in dest vector. The follow code would do the job – … Read more

[Solved] what does this loop means: for(j,0,np) [closed]

by

Okay. Thanks to @AshishJohn this question is now solvable. In the provided link you can see a define in the beginning which changes the syntax of for loops: #define for(i,a,b) for(i=a;i<b; i++) So for(j,0,np) will be converted by the preprocessor to: for (j=0; j<np; j++) which is a normal for loop. np is also declared … Read more

[Solved] better way to create game server with web interface

by

With your server code self hosted and a javascript client calling into your server methods, becoming your browser based client, your design should work. I am looking at this. https://learn.microsoft.com/en-us/aspnet/signalr/overview/deployment/tutorial-signalr-self-host But I think you’ll need to figure out scale out scenarios and server failure scenarios with the self host. In case there is a patch … Read more

[Solved] Why am I getting this output in C++? Explain the logic

by

NULL results in a false condition. You could imagine that NULL is a 0, so this: if(NULL) would be equivalent to this: if(0) thus your code would become: #include <stdio.h> #include <iostream> int main() { if(0) std::cout<<“hello”; else std::cout<<“world”; return 0; } where is obvious that because 0 results to false, the if condition is … Read more

[Solved] dynamically add column to model and show relevant field to add, edit and delete the field data in view asp.net mvc enityframework?

by

You cannot “dynamically” add a column to a table per row. If the user could add a column, then that column would be added to the table in general, and every row in that table would have it. Even if this was possible, it would require granting your application admin rights on your database, which … Read more

[Solved] How do I print out this string from within my class? [closed]

by

You can use operator-overloading and friend function. Also you will need to create an object of type ColorPicker because Color is instance variable. Note: Since Color is of string type hence, keep it as 1D array. Following is working code. You can see it working here: #include <iostream> #include <string> using namespace std; class ColorPicker … Read more
