Programming in C MCQ - Constants, Variables and Data Types
A constant represents a fixed value that does not change during program execution. This distinguishes it from a variable, whose value may change.
The presentation groups constants into numeric, character and string constants. These categories describe the forms of fixed values used in C programs.
An integer constant represents a whole-number value and therefore does not contain a decimal point. A sign may be used to express a positive or negative value.
-123 is a valid decimal integer representation in the presentation's examples. The other choices contain a decimal point, comma, or embedded space.
