I'm having a vector...
vector<Person> x;
... with a class I've defined (Person).
I have several elements in this vector and I would like to save it to a file (binary (?)). And later on open up this file to retrieve... (1 Reply)
using SUN C++ I have a problem when I do a push_back on a vector. The linker gives me a undefined symbol error on __cxa_end_catch.
Any ideas, is there a library to include?
Thanks

Hi
i have the following structure
struct S
{
char Mod_num;
char val;
char chr_nm_cd;
}
I am reading a 2GB file and inserting into the structure and writing into a vector.
I feel like only vector will be a right option. I tried with multimap but it is memory intensive and hence i... (1 Reply)
Hi! I need to make dynamic multidimensional arrays using the vector class. I found in this page How to dynamically create a two dimensional array? - Microsoft: Visual C++ FAQ - Tek-Tips the way to do it in 2D, and now i'm trying to expand it to 3D but i don't understand how is the operator working,...

I modified some code I found on Wikipedia concerning maps to see if it would work before applying it to a project I'm working on that has a similar idea.
What I would want is for a user to be able to enter sentences and then be able to distinguish how many times a the person entered a word in a... (4 Replies)
Hi all,
I have a vector,the type of the element within it is list<int>,and i wanna sort this vector.So i implemented a function as a predicate for sort(the STL algorithm).Problem came when i missed the bold part in my code,g++ generated lots of error messages.And after i added the bold... (4 Replies)
if i declare both but don't input any variables what values will the int array and file pointer array have on default, and if i want to reset any of the elements of both arrays to default, should i just set it to 0 or NULL or what? (1 Reply)
Hi all, from my understanding I understand that I can use array in this manner.
struct test
{
int a;
int b;
int c;
};
test testing; //creating an array with the structer type
testing.a=1;
testing.b=2;
testing.c=3;
If I'm not wrong we can use array in this manner,... (12 Replies)
hello guys.
i'm new to c++. i've problem using two dimensional vector.
i've a project of making conway's game of life. this is the code that i have made so far.
my problem is how can i give a two dimensional vector through main.
glider.vec1 = vec; is not correct way to give a two... (2 Replies)
In AWK
For 3 individual vectors of the form:
-2.772 -9.341 -2.857
-5.140 -6.597 -1.823
-2.730 -5.615 1.159
I would like to write a script that parses line by line to (i) normalise, (ii) divide by the norm for *each* vector.
I.e.
sqrt(-2.772^2 + -9.341^2 + -2.857^2)=10.154
