invalid conversion from âint*â to âintâ

[olove05]

the constructor is
TwoD<T>::TwoD( int x, int y)
{
r = x;

c = y;

elet = new int *[r];

for (int i = 0; i < r; i++){

elet[i] = new int [c];

}
for (int i=0; i < r; i++){

for(int j=0; j < c; j++){

elet[i][j] = i*j;
}
}
}

--------------------------

the swap function is

template <class T>
TwoDimArray<T> TwoD<T>::swap(int r, int c )
{
x=r;
y=c;

int *temp;
*temp = elet[x];
elet[x] = elet[y];
elet[xdim] =* temp;
}
---------------------------------
the errors are


P.cpp:30: instantiated from here
TwoD.cpp:153: error: invalid conversion from âint*â to âintâ
TwoD.cpp:155: error: invalid conversion from âintâ to âint*â

any idea fro the mistake ???

in the main the call is:
int main()
{
TwD<int> TwoD2

TwD2.swap( 3,4 );

return 0;
}

What's up with this syntax elet = new int *[r]; O.O ?

kevinchkin: That's perfectly valid.

I think you meant:

int *temp;
temp = elet[x];
elet[x] = elet[y];
elet[xdim] = temp;

[kevinchkin]

Oh yeah, Damn it, didn't see he was allocating the memory over there. Sorry, my bad.

Hi guys

the asswerd was ok but the result of the zwap was not????/

What is wrong in the swap, any edea

Well, your swap is probably wrong. The fourth line assigns to elet[xdim] instead of elet[y], for some reason.

[olove05]

yes, look like I do not saving any number and the destructor do his job????

any idea.........


this is after the call from main
