here is the code

cout<<"The Mean is "<<mean<<endl;


also this code is not working ,when I use the [ ] at the end,I am getting an error so I am using () instead but the calculation is incorrect.Please help

float var=((num[0]-mean)*pow(num[0]-mean,2) + (num[1]-mean)*pow(num[1]-mean,2) + + (num[2]-mean)*pow(num[2]-mean,2))/ (num[arraysize-1]);
