JNTU B.Tech I PROGRAMMING FOR PROBLEM SOLVING Previous Question Paper (September/October - 2021 - R18)

A flowchart is a graphical representation of an algorithm or a step-by-step process used to solve a problem. It uses standardized symbols such as ovals for start/end, parallelograms for input/output, rectangles for processing, and diamonds for decision-making, connected by flow lines to indicate the sequence of operations.

To generate the Fibonacci sequence up to n numbers:

1. Start.
2. Read the value of n.
3. Initialize variables: a = 0, b = 1, count = 0.
4. If count is less than n, print a.
5. Calculate next term: next = a + b.
6. Update variables: a = b, b = next, count = count + 1.
7. Repeat from step 4 until count equals n.
8. Stop.

In C, the auto storage class is the default for all local variables defined within a function or block. The auto keyword was introduced primarily for historical reasons and to maintain compatibility with the B programming language, from which C evolved.

While it is redundant in modern C programming, the keyword serves specific purposes:

• Explicit Documentation: It allows a programmer to explicitly declare the storage class of a variable, making the code's intent clear to others reading it, even if the compiler would have assumed it by default.
• Consistency: It provides symmetry with other storage class specifiers like static, extern, and register. By using auto, the programmer can explicitly specify the storage class for every variable, ensuring a uniform coding style.
• Future-proofing: In the C++ language, the meaning of auto was repurposed for type inference. Keeping the keyword in the C standard helps maintain a level of syntactical similarity between C and C++.
