Final answer:
To access a struct, use the dot operator for variables or the arrow operator for pointers. For a cell array, like in MATLAB, use curly braces to access specific data within the array.
Step-by-step explanation:
The correct way to access a struct in languages such as C and C++ is by using the dot (.) operator if you have a structure variable. For example, if you have a struct named person with a member age, you would access it as person.age. If you have a pointer to a struct, you use the arrow (->) operator, like personPtr->age. As for accessing a cell array in a language such as MATLAB, you use curly braces to access the data. For instance, cellArray{1,2} will access the data in the first row and second column of the cellArray.
For example, let's say you have a cell array called 'myArray' which contains a struct with a field called 'name'. To access the 'name' field of the struct at index 1, you would use the following syntax:
myArray{1}.name
