What is pseudocode in C?
- Learn from the Best in the Industry! What Is Pseudo-Code in C? The pseudocode in C is an informal way of writing a program for better human understanding. It is written in simple English, making the complex program easier to understand. Pseudocode cannot be compiled or interpreted.
How are operators applied in pseudocode?
- Specifically, operators in pseudocode are applied in this order: Operations in parentheses are resolved first, moving from left to right. *, / and MOD are resolved second, moving from left to right. + and - are resolved third, moving from left to right.
