Q.1. (a) Explain the structure of a C program. (b) Explain input/output functions (printf, scanf).

Ans 1.

(a) Structure of a C Program

A C program has a clear format that any programmer needs to comprehend before writing code. This design gives the program an orderly flow from starting to finish. Each component serves a particular purpose, and skipping any part can lead to error in the compilation process or poor output.

The first part is the Documentation Section. This section contains comments explaining the program’s purpose. Comments are composed using/ for single lines or /*/ for multiple lines. Comments are not considered by the compiler

Q.2. a) Explain the syntax and working of the switch-case statement in C. b) Compare for, while, and do-while loops.

Ans 2.

(a) Switch-Case Statement in C

The switch-case statement can be described as a flow control statement utilized to perform a section of code using a number of possibilities. It can be used as an alternative to an extensive chain of if-else-if statements. It’s especially helpful when a variable needs to be compared with

 

Q.3. Define operators in C and explain their types with suitable C Programs.

Ans 3.

Operators in C are specific symbols that carry out operations using one or more operands. They’re the fundamental building blocks of any C expression. C is a rich set of operators, each serving an individual purpose.

Types of Operators in C

1. Arithmetic Operators

Arithmetic operators perform basic mathematical calculation. They include + for addition Subtraction * to represent

Q.4. (a) Explain call by value and call by address. (b) Explain the difference between library and user-defined functions.

Ans 4.

(a) Call by Value and Call by Address

In C, when the function is invoked the arguments are passed by two ways calling by value as well as call by address. Each technique handles the data in different ways and have their unique advantages.

In call by value, an exact copy of the argument is given to the function. The function works with this copy, not with the original variable. Any modifications made by the function will not impact the original

 

 

Q.5. Explain standard string functions (strlen, strcpy, strcat, strcmp).

Ans 5.

C includes a library of strings that can be manipulated in the same way strings are manipulated in other languages, using the string.h header file. The functions allow using strings much easier and efficient. A string in C is an array of characters terminated by a null character ‘0’. String functions that

 

 

Q.6. (a) Explain advantages and disadvantages of recursion. (b) Explain function prototype and its importance.

Ans 6.

(a) Advantages and Disadvantages of Recursion

Recursion may be viewed as a method of programming where a limitless function is able to call itself to solve a problem. It divides a large problem into sub-problems, which are of the same kind. If you want to avoid repeating, every recursive function should contain the base case. If not specified, the function
