Today's Topic Decision Construction in C Language Solved Quiz

Q1) What is the simplest selection structure

1. Switch
2. If
3. If - else
4. Nested If

Answer:If

Explanation:The simplest selection structure in programming is the "if statement". The if statement is a programming construct that allows a program to make a decision based on a condition. It evaluates a Boolean expression and executes a block of code if the expression is true.

Q2) How many kinds of control structures

1. 3
2. 2
3. 5
4. 6

Answer:3

Explanation:There are three main kinds of control structures in programming: selection structures, iteration structures, and sequence structures.
Selection structures:
Iteration structures:
Sequence structures:

Q3) An if statement inside another if statement Is

1. If- Statement C)
2. Nested if statement
3. Switch statement
4. Defaukt

Answer:Nested if statemen

Explanation:A nested if statement is an if statement that is placed inside another if statement. This is a way of adding more conditions to an if statement, allowing a program to make more complex decisions based on multiple conditions.

Q4) Which keyword is not used in switch statemewe

1. Case
2. Default
3. If
4. Switch

Answer:If

Explanation:If

Q5) Arother term for conditional operator is:

4. Byte

Answer:Ternary

Explanation:The conditional operator are also known as the ternary conditional operator, evaluates a Boolean expression and returns the result of one of the two expressions,

Q6) Choose an alternative to the If-else statement from the following

1. Logical operator
2. Relational operator
3. Conditional operator
4. Arithmetic

Answer:Conditional operator

Explanation:The conditional operator, also known as the ternary operator, is another alternative to the if-else statement. It is a concise way of writing a simple if-else statement and can be used in many programming languages, including C and C++.

Q7) Which keyword is used for loop?

1. if
2. While
3. loop
4. Nested

Answer:while

Explanation:while

Q8) Which of the following are valid case statements in switch

1. case x < 5
2. case 'ab'
3. Case ¢
4. case 1.5;

Answer:case 'ab'

Explanation:case 'ab'

Q9) In If-statement false represented by:

1. 0
2. 1
3. 2
4. 3

Answer:0

Explanation:0 Represents the off Or False Situation in digital devices

Q10) Which operator in C is called ternary operator?

1. +
2. ?
3. if
4. --

Answer:?

Explanation:The ternary operator in C is the conditional operator, also known as the "?:" operator. It is called the ternary operator because it takes three operands: a condition, a value to return if the condition is true, and a value to return if the condition is false.

Q11) Which programming structure makes a comparison?

1. Decision
2. Relation
3. Sequence
4. Repetition

Answer:Relation

Explanation:A selection structure, such as the if statement or the switch statement, is a programming structure that makes a comparison. These structures allow a program to check a condition or make a decision based on the value of a variable or expression.

Q12) Another term for computer making a decision is:

1. Sequence
2. Iteration
3. Selection
4. Repetition

Answer:Selection

Explanation:"selection" is another term for computer making a decision.

Q13) In If-statement, true is represented by:

1. 1
2. 0
3. 2
4. 00134

Answer:1

Explanation:1

Q14) The conditional operator is used as alternate to:

1. If
2. else
3. If- else
4. Switch

Answer: If- else

Explanation: If- else

Q15) Conditional operator takes:

1. Two
2. Three
3. One
4. four operand

Answer:Three

Explanation:The conditional operator, also known as the ternary operator, takes three operands. The first operand is a Boolean expression or condition that is evaluated to either true or false. The second operand is the value that is returned if the condition is true, and the third operand is the value that is returned if the condition is false.

Q16) If a relational expression is true, It has a value:

1. .0
2. 1
3. -1
4. None of these

Answer:1

Explanation:1

Q17) An expression that uses a relational operator represented by: (A) (B) (C) !

1. Sequential
2. Serials
3. Operational
4. Relational

Answer:Relational

Explanation:An expression that uses a relational operator compares two values and returns a Boolean value (either true or false) based on the result of the comparison. Relational operators are symbols used in programming languages to compare values.

> : greater than
< : less than
>= : greater than or equal to
<= : less than or equal to
== : equal to
!= : not equal to

Q18) Graphical representation of a program is called:

1. Logic chart
2. Binary chart
3. Flow chart
4. E-R chart

Answer: Flow chart

Explanation: A flowchart is a graphical representation of a process or algorithm that uses symbols and arrows to show the sequence of steps or actions. Flowcharts are used in computer programming, business processes, and other fields to help visualize complex processes and identify areas for optimization or improvement.

Q19) Which of the given is used for making two way decision?

1. If See
2. if-else
3. Nested If
4. Switch

Answer: if-else

Explanation: if-else

Q20) Which of the following is the simplest form of the decision structure?

1. If Statement
2. if-else
3. Nested if
4. Switch

Answer: if

Explanation: if

Q21) Switch statement is an alternative of:

1. If- else
2. nested -if
3. if- else
4. If

Answer:If-else

Explanation:The switch statement is an alternative to the if-else statement in programming. Both the switch statement and the if-else statement are selection structures that allow a program to make decisions based on the value of a variable or expression.

Q22) Which of the following is valid case statement in a switch statement:

1. Case 1:
2. Casex<1:
3. Casex>1:
4. Case 1.5:

Answer:Case 1:

Explanation:Case 1: Conceptual. The keyword case and then its id or identifer

Q23) The last statement of each case block in switch () structure must be:

1. Default
2. End Select
3. Break
4. End

Answer:Default

Explanation:The default case in a switch statement is not considered as a case block, so it does not require a break or a return statement at the end.

Q24) The case block in switch () structure ends with:

1. Default
2. End Select
3. Break
4. End

Answer:Break

Explanation:Break

Q25) This statement causes a loop to terminate early:

1. Exit
2. Break
3. None of these
4. Terminate

Answer:Break

Explanation:In programming, the break statement is used to terminate the execution of a loop, a switch statement or a labeled block.
