Chapter 11: Problem 57

Each of the following declarations, programs, and program segments has errors. Locate as many as you can. struct { int x; float y; };

Short Answer

Expert verified
Answer: The main issue with the given structure declaration is that it does not have a name. It can be fixed by assigning a proper name to the structure, such as "Point", allowing instances of the structure to be created.

Step by step solution

01

Assign a Name to the Structure

Assign a proper name to the structure, for example "Point". This way, the structure can be properly used later in the program. struct Point { int x; float y; }; Now the structure can be used in the program by declaring instances of the structure.
