Later, her teacher tells her that this approach is called procedure-oriented programming (POP). The teacher also explains that in
POP, more emphasis is given to functions rather than data. However, while testing her program, Riya notices that although the
program runs successfully, it gives the wrong output because she used the wrong formula.
Based on the given case, answer the following questions:
1. Which programming approach is Riya using?
a. Object-oriented programming b. Procedure-oriented programming
c. Machine language d. Assembly language
2. In POP, more emphasis is given to:
a. Data b. Objects
c. Functions d. Classes
3. The program giving wrong output despite running successfully is an example of:
a. Syntax error b. Runtime error
c. Logical error d. Compile-time error
4. Sharing data between functions through global variables is a characteristic of:
a. OOP b. POP
c. Applets d. High-level abstraction
