Question

I have defined double variable for my .h class like this

double *i;
double *j; 
double *k; 

Now I call that variable in my .m file like this

i = j+k;

but its showing error like this,

invalid operands to binary expression 'double' and 'double'

I’m new to iPhone and objective c environment guide me how can I call that.

Remember that Objective C is a superset of C. So primitive data types (int, float, double) remain primitive. Try without pointers:

double i;
double j;
double k;
