10th Class Computer Science Chapter 1 Programming Techniques Short Questions Answer
The design in which a problem is divided into smaller sub problems to approach the solution is called top down design.
Logical error occurs when a program follow a wrong logic the translator does not display any error message for logical errors
Debugging is the process of finding and removing error in the program.
A syntax error occurs when the problem violates one or more grammatical rules of the programming language
1. Problem identification
2. Specify requirement
3. Analyze the problem
4. Design algorithm and draw flowchart
5. Implement the program
6. Document the program
7. Maintain and update the program
The grammatical rules of a programming language to write programs are referred to as syntax of that programming language.
The process of understanding the problem for developing its solution is called the analysis problem.
A runtime error occurs when the program directs the computer to perform an illegal operation such as dividing a number by zero.
Problem solving is a skiing which can by developed by following a well organized approach.
The process of converting an algorithm to a program using a programming language is known as coding.
1. Investigation
2. Preliminary algorithm
3. Refining the algorithm
1. It is difficult to draw flowchart for complex problems
2. If alterations are required the flowchart is to be redrawn
A syntax error occurs when the program violates one or more grammatical rules of the programming language. These are detected during the execution of a program. Computer displays an errors message
Documentation is a detailed description of a programs algorithm design coding method testing and proper usage.
Algorithm development involves the following steps to carry out
1. Step Investigation
2. Preliminary algorithm
3. Refining the algorithm
To solve a problem on a computer it is necessary to know the syntax otherwise an error is occur is known as syntax error. A syntax error occurs when the program violates one or more grammatical rules of the programming language.
Program maintenance is the process of upgrading the program to accommodate the new requirements of the users and to correct errors in the program.
Flow lines represent the direction of flow of information in the flowchart between various blocks.
When a program does not produce desired result then contain the error. These errors are called bugs.
Designing he program is very important is problem solving. The problem can only be saved successfully if an efficient program is designed.
is stands for connector
Analyzing is the decomposition of a bigger problem in sub-problems At this stage the big problem decomposed into sub-problems Rather on concentration the bigger problem as a whole we try to solve each problem separately It leads to a simple solution.
An algorithm is a finite set of steps which if followed accomplish a particular tasks.
Logical Eros are the most difficult errors to locate or find because the translator compiler or interpreter does not report any error message for a logical error.
BEGIN
Sum
N=0
DO WHILE
Sum= Sum+N
PRINT Sum
N=N+1
END DO
END
two advantages flow chart is
1. The flow chart helps in debugging process.
2. With the help of flow chart the logic of an algorithm can be described more effectively.
1. Procedure started
2. Take input of average speed as V and times as T
3. Calculate the value of S as
4. Print
5. Stop the procedure
Algorithm
Begin
PRINT ENTER RADIUS
AREA
PRINT AREA
END
1. Processing
2. Connector
3. Flow lines
Desk checking is an important part of algorithm design Once the algorithm has been designed it should be verified through desk checking To desk check an algorithm we must carefully perform each algorithm and verify that the algorithm works as desired.
