JohnGraham: Would const be useful if the struct was as follows?
Yes, (assuming you want all the elements of your array to be const) since that's qualifying the array. It seemed like you wanted to make a const type (which you could do with a typedef).
I am using a structure defined as follows
struct gene_square
{
double *x;
double *y;
};I have class, with a member function which is a pointer of this type:
gene_square* m_Genes;I am allocating memory in the constructors like this:
m_Genes = new gene_square;
for (ii=0;... (1 Reply)
Hi All,
My latest assignment (practice not coursework!) is to write prototype interactive exam/test console application. I've used structs to store the question information (not sure if this was the best way to do it?) and I have the following code that outputs each question and it's possible... (0 Replies)
I have two or more linked lists that have the same names for their "next". For example,
struct server_t {
sockaddr_in * sin;
server_t * next_;
}
struct player_t {
char name;
player_t * next_;
}
How can I get a function to take in either type and manipulate the pointers?
I... (3 Replies)
Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)
Hi, i'm trying to copy a struct into a binary file using the unix instruction write, so i declare and fill the struct "superbloque" in one function "initSB" and then i pass the pointer to another function called bwrite (for block write) which calls write. The problem is that i call the function... (2 Replies)
I am trying to work out the best syntax for a relatively simple operation. The goal is to declare an instance of a struct and pass it around to be populated and have the data manipulated. There is an extra wrinkle in that the functions are in different src files.
The main is simple,
#include... (5 Replies)
Hi,
I have received an application that stores some properties in a file. The existing struct looks like this:
struct TData
{
UINT uSizeIncludingStrings;
// copy of Telnet data struct
UINT uSize;
// basic properties:
TCHAR szHost; //defined in Sshconfig
UINT iPortNr;
TCHAR... (2 Replies)
In C++ there is a struct with the following structure:
typedef struct myStruct
{
string s_date;
float fA;
float fB;
float fC;
.....
float fZ;
} myData;
After some computations on the values of the struct members are inserted into a database table:
myData... (4 Replies)
Store args passed in array but not the first 2 args.
# bash
declare -a arr=("$@")
s=$(IFS=, eval 'echo "${arr}"')
echo "$s"
output:
sh array.sh 1 2 3 4 5 6
1,2,3,4,5,6
Desired output:
sh array.sh 1 2 3 4 5 6
3,4,5,6 (2 Replies)
