Pseudocode

Learn to write algorithm steps in readable pseudocode.

What is pseudocode?

Pseudocode writes algorithm steps in a human-readable form. It expresses the logic without being bound to a real programming language's syntax.

It uses constructs like if, for, while but details like declarations or semicolons are flexible.

Pseudocode for the larger of two numbers: if a > b: return a else: return b. This checks a condition and picks a branch.

Pseudocode shows steps in order and clearly. You can translate the same logic into Python, Java or C++ code easily.

Write max_of_two(a, b). Return a if a > b, else b. Print 9 with print(max_of_two(4, 9)).

Show example solution

def max_of_two(a, b):
    # Find the larger
    if a > b:
        return a
    else:
        return b
print(max_of_two(4, 9))
