Explain the concept of Algorithms in C.
Answer:
Algorithm:
An algorithm is a well-defined sequence of instructions designed to solve a specific problem. It's
a step-by-step procedure that, when followed, leads to the desired outcome. Importantly, an
algorithm should always have a clear stopping point.
Rules for Algorithms:
(1) Inputs and outputs should be defined precisely: The algorithm must clearly specify what
data it takes as input and what result it produces as output.
(2) Each step in the algorithm should be clear. Every instruction within the algorithm must
be easily understandable and leave no room for interpretation.
(3) An algorithm should be most effective among many different ways to solve a problem.
(4) An algorithm should not have computer code. Instead, the algorithm should be written in
such a way that it can be used in similar programming languages.
(5) Algorithms are conceptual solutions and should be expressed in a
language-independent manner, often using pseudocode or natural language, so they
can be implemented in various programming languages like C, Python, Java, etc.
1) Algorithm for adding two
numbers:
Step 1: Start
Step 2: Declare variables n_1,
n_2
Step 3: Read values n_1, n_2
Step 4: Add n_1, n_2 and assign
result to sum: sum
\leftarrow n_1 + n_2
