How to fix error: "request for member which is of non-class type"? P: 19 kino Hello, I am getting the following error 25 C:\Dev-Cpp\main.cpp request for member `no' in `one', which is of non-class type `box[12]' in the code Expand|Select|Wrap|Line Numbers while(!myfile.eof()) { for(inti=0;i<12;i++) { myfile>>one.no[i]; } } where 'one' is an object of struct type 'box' and 'no' is the variable inside the struct. The above bit of code is just the simplified version of my complete code but basically I declared an array of struct type 'box' (size=12) , named it 'one', and am currently reading some numbers from a file into the variable 'no' of the struct.
