Chapter 11: Problem 51

T F In a union, all the members are stored in different memory locations.

Short Answer

Expert verified
Answer: False

Step by step solution

01

Understanding a union in programming

A union in programming is a data structure that allows to store different data types in the same memory location. It can hold only one of its members at a time. The size of a union is determined by the size of its largest member, as they share the same memory space.
02

Comparing Unions with Structures

Unlike unions, a structure is a data structure in which all the members have their own memory locations. The size of a structure is the sum of the sizes of all its members. In a structure, it is possible to store values of all its members simultaneously, but in a union, only one value can be stored at a time.
03

Verifying the statement

Now let's see if the statement is true or false. "In a union, all the members are stored in different memory locations." As discussed in Steps 1 and 2, the members of a union share the same memory location, which means they are not stored in different memory locations.
04

Conclusion

Based on our analysis, the statement is false (F). In a union, all the members are not stored in different memory locations. They share the same memory space.

What is the difference between a union and a structure?

Define an array of 35 of the car structure variables. Initialize the first three elements with the following data: $$\begin{array}{llll} \text { Make } & \text { Model } & \text { Year } & \text { cost } \\ \text { Ford } & \text { Taurus } & 1997 & \$ 21,000 \\ \text { Honda } & \text { Accord } & 1992 & \$ 11,000 \\ \text { Lamborghini } & \text { Countach } & 1997 & \$ 200,0000 \end{array}$$
