10th Class Computer Science Chapter 3 Input and Output Handling Short Questions Answer

[toggle title=”What is the difference between ERR and ERL variables? ” state=”close”]
ERR When an error occurs its code is assigned to a special variable named ERR.
[/toggle][toggle title=”What is meant by transfer of control? ” state=”close”]
Transfer of control transfers the flow of execution of a program from one part of the program to another part there are two types of transfer of control
Conditional Transfer of Control
Unconditional Transfer of Control
[/toggle][toggle title=”What is the purpose of conditional transfer of Control? ” state=”close”]
The conditional transfer of control causes the switching of the control from one part of the program to the other depending on a certain condition GOTO n1,n2,n3
[/toggle][toggle title=”What is selection structure? ” state=”close”]
Selection structure decide which substitute program is to be executed In GW-BASIC we use the IF THEN and IF THEN ELSE statements to apply selection structure.
[/toggle][toggle title=”What is the purpose of unconditional transfer ‘F’ control? ” state=”close”]
The unconditional transfer of control transfers the control from one part of the program to the other without any condition In this unconditional transfer of control the program control switches to a specific line by skipping one or more lines without any condition.
[/toggle][toggle title=”What is the purpose of ON ERROR GOTO statement? ” state=”close”]
This command enables error trapping feature of GW-BASIC and specify the first line of error handing routine.
[/toggle][toggle title=”Write the types of control structure? ” state=”close”]
There are three types of control structure these care sequence selection and loop.
[/toggle][toggle title=”How does IF-THEN ELSE statement work in BASIC? ” state=”close”]
The IF-THEN-ELSE statement is a decision making statement as it decides the path of the program It helps in making comparison and testing whether a condition is true or not.
[/toggle][toggle title=”Define sequence structure? ” state=”close”]
In Sequence structure instruction are executed according to the increasing order of their line number.
[/toggle][toggle title=”Write down the syntax of ON GOTO statement? ” state=”close”]
The Syntax of ON GOTO expression GOTO n1,n2,n3
Interpretation:
The expression is a valid BASIC expression and n1,n2,n3 are the valid number in the program where the control will be transferred. The range of value of numeric variable or expression is 0 to 255
[/toggle][toggle title=”When the WHILE WEND is useful? ” state=”close”]
This is useful where the programmer does not know in advance how many times the loop will be executed.
[/toggle][toggle title=”Explain the purpose of GOTO statement and write down its syntax? ” state=”close”]
GOTO statement is used to unconditionally transfer control from a program line to specific line without of the normal program sequence.
[/toggle][toggle title=”Define selection structure? ” state=”close”]
A selection structure chooses which alternative program statement to execute.
[/toggle][toggle title=”How many types of loop? ” state=”close”]
There are three types of loop.
i. FOR …………… NEXT LOOP.
ii. WHILE…………. WEND LOOP
iii. NESTED LOOP
[/toggle][toggle title=”Which statement are used to control iterations in BASIC? ” state=”close”]
Control of Iteration: Loop statements are used to control iteration in Basic language for this purpose FOR NEXT and WHILE WEND loop structures are used.
[/toggle][toggle title=”Define control structure? ” state=”close”]
Control structure control the flow of execution of a program.
[/toggle][toggle title=”Define unconditional transfer of control? ” state=”close”]
In unconditional transfer of control the program control switches to a specific line by skipping one or more lines without any condition.
[/toggle][toggle title=”Define ERR? ” state=”close”]
When an error occurs its code is assigned a unique code to a special variable named ERR.
[/toggle][toggle title=”How many types of control structure in BASIC? ” state=”close”]
There are three types of control structure in BASIC
1. Sequence structure
2. Selection structure
3. Loop
[/toggle][toggle title=”What are the name of logical operator? ” state=”close”]
There are three logical operator AND, OR, NOT.
[/toggle][toggle title=”What is the syntax of IF THEN statement? ” state=”close”]
1. If expression THEN statement
2. If expression then line number
[/toggle][toggle title=”How we can exit from an error handing routine?
We can exit from an error handling routine using the resume Next Resume line number or END statement.
[/toggle][toggle title=”When the WHILE WEND is useful? ” state=”close”]
This is useful where the programmer does not know in advance how many times the loop will be executed.
[/toggle][toggle title=”Age of different candidates appearing before a selection board of PIA is accepted through the keyword? ” state=”close”]
1. INPUT AGE A
2. IF A THEN 30 ELSE
3. PRINT Candidate eligible
4. GOTO 60

6. INPUT Would you like to input again
[/toggle][toggle title=”When we require loop structure? ” state=”close”]
We often face problem whose solution may require executing a set of statement repeatedly in such situation we use loop structure.
[/toggle][toggle title=”What is IF THEN ELSE statement? ” state=”close”]
The keyword ELSE is used to specify two different alternative with IF statement.
[/toggle][toggle title=”Write a program to print the table of given number” state=”close”]

30 Area = 3.14 r*r*
40 CIRCUM = 2*3.14
50 PRINT Area of the circle Area
60 PRINT Circumference of circle CIRCUM
