i'll try getline().thank you everyone.

thats the function given to me.as far as i know iostream& is in stringstream as ss is in that form from the given test core.i could be wrong.

i tried but it says &inStream doesnt have .str() member

How do I convert from std::stringstream to std::string in C++?

Do I need to call a method on the string stream?

i tried .str() but didnt work.




//cpp

urgh dont quite understand what anon trying ti say there



mind to explain to me how this works? really confuse now. =_=

and what do you mean with the return type must be correct.what i did...

Vector &Vector ::operator =(const Vector &num);

doesnt the argument for the operator = have to be a Vector& not an int.
i tried to use pointer but it didnt work.

i also even tried to create a...

v is a vector<int> v.
im doing it in class.
i've done most of the part for the function


Vector &Vector ::operator [](const unsigned int index);


but my prob is how can i get the value...

here's the problem.
i was given a test case v[0]=1.
in order to implement operator[],i need to get the access the value it is refering to which is 1.but im not sure how?





//initial test...

thanks! i get it now :)

can anyone help me to understand how the compiler knows which objects we are refering to in class.
let say there are two objects with the same function methods:
obj a;
obj b;
and there is a...

so,is this right?
im assuming what you are trying to say is this can be any object which in this case is v1 and x is v2 .




if (this->somefunct != x->somefunct){
....}

//core unit test
//given 2 constructors

vector v1;
vector v2 (5,3);

//member functions : int dotProduct(const Vector &x)

int n = v1.dotProduct(v2)

hope anyone here can point out where my mistake was.tyvm. :)

i am tryinh to create stack using linked list.

hey i fix it! LOL..
after all the hours i spent on this stupid error..i figure out how to solve it..

i just need to change

#


//my bad!

anyone knows how to fix this...



i couldnt figure out why it does this everytime i tried to do a simple cout on the pointer that carries the data




cout << ptr-> data

hey iMalc.
do you mean i need to initialise the new array i created then i can use it later on?..but how?
most of the examples i've seen didnt initialise the new array.

another que: do you know...

i understand that..but in order to create stack that is not possible.i cant use STL or vector for this stack assignment..so im trying to understand how pointers works then...

the way i think is:...

hi all..
i'm a bit confused how the pointer works..




std::string n;

//is this right??

having issue with stack using linked list.

1) the num didnt give any value tho with the cout in count()

2) how to return string from pop()? i tried many ways like return ptr->s and stuff but...

if i want to use realloc..how should i define the type..is it char? isnt this means it will only look into each character in the string but not as a whole string?

i tried the append method and i dont think it will works the way i want it to.


void Stack :: push(std::string n){
//create new space when adding element
const char* n2= n.c_str();...

for this practice,we are not allowed to use othe standard lib besides the string class...so what i trying to do here to create a new space for a string.

any hints?

thanks.

this is what i got so far..



void Stack :: push(std::string n){
//create new space when adding element

if (size+1 < maxItems ){
maxItems *= 2;
char*array=new char[maxItems];
