about delete[]

[hyena]

I have following code:


void free(double** a){

for(int i =0; i< 100;i++){
delete[] *(a+i);
}
}

double** t;
t= new double*[100];
for(int i =0; i< 100;i++){
*(t+i) = new double[100];
}

the idea is to create two dimensional array and use free() to free up the
memory, will this work?

I have following code:


void free(double** a){

for(int i =0; i< 100;i++){
delete[] *(a+i);
}

delete [] a; // don't forget to delete the primary array too.

}

double** t;
t= new double*[100];
for(int i =0; i< 100;i++){
*(t+i) = new double[100];
}

Yes, but it's best to use a matrix class. There are plenty of posts and
free libraries that show the matrix class.
