C :: Type Cast To Char

May 7, 2014

I have this program.

Code:
int test_variable;
int main() {
test_variable = (int)0x12;
}

Now my doubt is what is the advantage of type casting 0x12 to int. suppose if the test_variable data type is "char" then should i type cast to "char"?

C++ :: Forceful Type Cast Not Working

Mar 6, 2015

I am writing a program with FLTK and in event handling part wanted to send the address of the handler function to callback function. Type cast just does not work.

Code: btnOpenDB->callback(&FLUI::WndMain::DBOpenBtnClick_scb, reinterpret_cast<void*>(&WndMain::DBOpenBtnClick_cb));

I want to cast "a pointer to a class member function which accepts one argument" to a void pointer. After all it is just an address. So it is logically possible to cast it. Isn't it? Actually an static_cast should be enough!

C++ :: Integer Max - Long Data Type

Jan 4, 2013

Working on a Project Euler problem and the question asks for the largest prime number that is a factor of 600851475143. As you can see, this is significantly larger than the maximum of a long data type, which maxes out at 2147483647.

I'm running on Windows 32, so int64 is not a valid option for me. It seems like I'll likely have to use a different language to solve this problem.

C Sharp :: Call That Counts Number Of Entries In Database - Cast Error

Jul 14, 2013

I have an issue with a database call. I've got a database call that counts the number of entries in the database:

        private static Int32 dbCount() {
            SqlCommand cmd = new SqlCommand("SELECT COUNT (*) FROM Employees", conn);
            conn.Open();
            Int32 count = (Int32)cmd.ExecuteScalar();
            conn.Close();
            return count;
        }  

Afterwards I'm using this as a check throughout my application:

           if (dbCount > 0)  {
                // do something
            }  

When I execute this code I'm getting the following error: "Operator '>' cannot be applied to operands of type 'method group' and 'int'"

So I'm guessing it has something to do with the cast of the dbCount-object but I don't understand why as I already stated that the count-object to be an Int32.

C :: Cast Of The Pointer To Array

Dec 7, 2013

In my refference book I have got a example with a part saying to access the a[4][0] element of the array (named a) with pointer this can be written:

*((int*)a+4)

I wonder if the cast is really required. The book says it is required so that the pointer arithmetic can be done properly. However I am not sure about it. When I work with pointers defined by myself I don't use casts similar to this one. Is there a difference between a self defined pointer and array name?

C++ :: Changing Array Of Numbers Of Type Char To Type Int?

Apr 27, 2013

I'm having some problems with changing an array of numbers of type char to type int. Every time i try to sum 2 array indexed values it returns some letter or symbol. Also, if i change the type of the array in the functions the compiler gives me an error message. I would also like to add that the problem requires that the first two arrays be char so each individual number gets assigned to a different value.

My current code is:

Code:
#include <iostream>
void input(char a[], char b[], int& size_a, int& size_b);
void convert(char a[], int size);
void reverse(char a[], int size);
void add(char a[], char b[], int c[], int size);
int main()

[Code]....

C :: Cast Int To Char

Oct 2, 2014

Is it possible to get the string representation of an int. So I mean if i have: 5, I want to get '5'.

I was searching in the internet and I found this solution:

Code:
int number = 5;
char c = number + '0'; which works fine for small numbers, but if I do:
Code: int i;
char c;
for(i =0; i < 10000; i++) {
c = i + '0';
printf("%c
", c);
}

At some point some strange sings like %&/)/)$%&) are appearing, But i really need this huge numbers as well .. Is there any other way to do this??

C++ :: Cast Int To A String

Sep 29, 2013

How to cast an int to a string I came across this code:

#include <iostream>
#include <string>
int main(){
double f = 23.43;
std::string f_str = std::to_string(f);
std::cout << f_str << '
';
}

Unfortunately, using Dev C++ Version 5.4.2, I'm getting an error:

[Error] 'to_string is not a member of 'std'

C++ :: Dynamic Cast With Reference

Jun 20, 2013

Here is the code,

Code:
class B {
};
class D1:public B {
};
class D2:public D1 {
};

int main() {
B& b = dynamic_cast<B&>(*(new D2));
return 0;
}

D2 is actually grandchild of B, so D2 object reference can still be converted to B reference without any exception. Is it legal?

C :: Cast To Character Pointer For Printf

Apr 18, 2014

I cannot get the following to compile. The problem is the printf on the last line. I understand that printf requires a char (or pointer to char). I understand that I can convert between datatypes by putting the target data type in parenthises in front of the variable. But how do I cast the integer into a character and then get it's pointer to pass into printf?

Following is my code. I compile with gcc temp.c -o temp.

Note that I have tried many attempts at that last line and this is just the one that I really, really think should work (or is at least the closest to the correct answer).

This code shown below, using printf("%s", &(char)nextChar); returns

temp.c:26: error: lvalue required as unary '&' operand

If I try to use printf("%s", *(char)nextChar); I get the error

temp.c:26: error: invalid type argument of 'unary *' (have 'int')

This line printf("%s", (char)nextChar); returns the obvious

format '%s' expects type 'char *', but argument 2 has type 'int'

Code:

#include <stdio.h>
int main() {
printf("hello, world
");
#if defined(SUNDIALS_EXTENDED_PRECISION)

[Code] ....
