2nd PUC Electronics C Programming Two Marks Questions and Answers
Question 1.
Write the commonly used directive.
Answer:
# include<stdio.h> and #define pi 3.1415.
Question 2.
What does #include directive specify?
Answer:
#include directive specifies an external file containing functions or macro definitions which can be included as a part of a program.
#include<stdio.h> includes standard function to perform input and output operations.
Question 3.
Briefly explain #define directive.
Answer:
#define directive is a compiler directive and not a statement. If this statement is included in the -program at the beginning, then the pre-processor replaces every occurrence of the identifier in the source code by the constant/string. For example if the statement is #define rate 20 then in the program whenever variable rate is considered then it is always assigned with constant 20.
Question 4.
Briefly explain #include directive.
Answer:
#include directive specifies an external file containing functions or macro definitions which can be included as a part of a program.
#include<stdio.h> includes standard function to perform input and output operations.
Question 5.
Write the steps involved in executing a C program.
Answer:
Steps involved in executing a C program are
- creating a program
- compiling the program
- linking the program with functions needed from C library and finally
- executing the program.
Question 6.
What are the different types of errors a programmer do?
Answer:
Generally, programmers do three types of errors namely syntax error, logical error and run time error.
Question 7.
Briefly explain syntax error.
Answer:
Syntax error is the result of violating the grammar of C programming language. When these errors occur, computer display an error message specifying the line number where the error has occurred. In the program segment
int a,b,c
a=20, b=c; computer will indicate semicolon is missing.
Question 8.
Briefly explain logical error.
Answer:
As the name implies Logical errors are related to the logic of the program execution. Logical errors do not show compiler generated error messages rather they cause wrong results. These errors are primarily due to poor understanding the problem, incorrect translation of the algorithm into program and lack of clarity of hierarchy of operators. In the statement if(x= =y) printf(“They are equal\n”); when x and y are float type, they rarely become equal due to truncation errors. The printf may not be executed at all. Similarly test condition while(x!=y) might create an infinite loop.
Question 9.
Briefly explain run time error.
Answer:
When the user tries to run ambiguous instructions run time error occurs. Errors of mismatching the data types, referencing out of range array element cannot be detected by the compiler. Divide by zero, data overflow are some examples.
Question 10.

2nd PUC Electronics C Programming Four Marks Questions and Answers
Question 1.
Write the features of C.
Answer:
C is a powerful, flexible language that has gained worldwide acceptance in recent years. C is concise, yet powerful in its scope. It is a high-level language that also incorporates features of low-level languages. It is becoming the standard for program development on small machines and microcomputers.
It is possible to apply C to nearly all application areas. Modularity {process of dividing problems into sub-problems) makes C ideal for projects involving several programmers. C permits nearly every programming technique. C is widely available for most brands and type of computers. It is portable. With all the features C is not a difficult language, it is one of the easiest languages to learn and implement.
C programming can be used to write any complex program because of its rich set of built-in functions and operations. C compiler combines the capabilities of an assembly language with the feature of high-level language and therefore it is very much suited for uniting both system software and business packages. Because of its variety of data types, powerful operator programs in C are efficient and fast. C has the ability to extend, it means user-defined functions can also be added to C library.
Question 2.

Subprogram Section Function 1 Function 2 Function 3 Function 4 ………………… (User-defined functions) Function n |
Question 3.
Briefly explain the format of a simple C program.
Answer:
Every C program you create includes the following components
Pre-processor directives
main( )
A pair of flower brackets { }
Declarations and statements
User created sub-programs or functions
{
Declarations and statements
}
User created sub-programs or functions
The above-described components are organized as follows
Pre-processor directives
main( )
{
Declarations and statements
}
User created sub-programs or functions
Pre-processor Directives
A C program contains one or more functions or sub programs. Function is a series of instructions to the computer to perform a specific task. Many functions are already written and compiled in the library supplied. Instead of writing the individual instructions user can tell the compiler to use one of its standard functions. Identifying the class of functions to be used is done in the pre-processor directive.
#include <stdio.h>
#include <string.h>
are some examples of pre-processor directives.
main ( )
Every C program must begin with the function called main( ), which is the identification for the start of the main part of the program and it looks just like main( ).
The parentheses after main( ) are part of the function name and are necessary. They tell the compiler that function is referring to and not the word main. A pair of parentheses must follow every function.
A pair of flower brackets { }
Following main( ) are declarations and statements. An opening brace must appear immediately after the word main( ) and closing brace “}” must follow the last instruction. The flower brackets or braces thus indicate the body of the program, which includes instructions to perform the required task.
Declarations and Statements
The declarations represent that part of the program where all the variables, arrays, functions and so on are identified with their data types. Sometimes the various elements are initialized in this part. The statements can include instructions to perform certain operations such as input or output or assignment. Statements can also include C commands or the names of functions in the library.
Question 4.
Draw the flowchart to show the process of compiling and running C program.
Answer:
Flowchart is shown in fig. 1.
Question 5.
Write the rules for forming the identifier name.
Answer:
Rules to be followed while creating identifiers:
- The first character of an identifier should always start with an alphabet or an underscore, which can be followed by either alphabets or digits or certain symbols.
- An identifier may be of any length up to 32 characters. Some compilers limit the length to eight characters.
- Identifiers can contain both uppercase and lowercase letters. C is case sensitive, that is, lowercase letters are not converted to uppercase letters when used in identifiers.
- Special characters except underscore should not be used in identifiers. Successive underscores are also not allowed.
- Identifiers should be single words i.e., blank spaces cannot be included in identifiers.
- Reserved words should not be used as identifiers.
Legal identifiers | Illegal identifier | Legal but poor |
Sum Emp_name Student_address Number age |
Varun’s_addr while @total sum do-it counter 3by2 |
_help sumo_1 |
Question 6.
Write the rules for forming a variable name.
Answer:
- Variable name consists of Setters, digits & underscore (_)
- Must begin with a letter. Some systems permit an underscore as the first character.
- ANSI standard recognizes a length of 31 characters. However, the length should not be normally more than 8 characters, since only the first eight characters are treated significant by the compiler.
- Uppercase and lowercase are significant, ie TOTAL is not same as total or
- Variable name should not be a keyword.
- White space is not allowed.
Example: Valid: temp, avg, suml ,total, ph value, T_raise, mark, i, j Invalid: 123,25th 5times, (area) abc$ char, int, group one abc-5
