Question

Rewrite the following program segment:

Using if else:

String grade = (marks>=90)? "Grade is A" : (marks>=80)? "Grade is B" : "Grade is C";​

Answer 1

Python

Concept

• The questions comes under the topic conditionals expressions.
• An if-elif-else ladder is formed.
• Only one of the the these statements is printed based upon the trueness.
• elif will be considered when the conditions in the if becomes false. For example: marks is 85. In this case , elif will be executed.
• Likewise else is executed in case if and elif both doesn't hold.

Program

marks = int(input("Enter your marks here:\n"))

if (marks >=90):

   print("Grade is A.")

elif (marks >=80 and marks < 90):

   print("Grade is B.")

else:

   print("Grade is C.")

Answer 2

Required program:-

Question:

• Rewrite the following program segment:

Using if else:

String grade = (marks>=90)? "Grade is A" : (marks>=80)? "Grade is B" : "Grade is C";

Answer:

if (marks >= 90)

grade = "A";

else if (marks >= 80)

grade = "B";

else

grade = "C"

Step by step explaination:

If statement is you have seen so far allow you to execute a statement of the condition evaluates to true. For such scenarios, the else-if control is used. The statement that has to be executed when the condition evaluates to false is written under the else-part.

The if-else construct takes the following syntax:

if (condition 1)

statement1;

else

statement2;

Note:

Statement1 is executed when the condition is true.

statement2 is executed when the condition is false.

______________________________

In such a ladder, the if statements are executed from the top to bottom as per the following logic:

♦ As soon as one of the conditions becomes true, the statement associated with that if will be executed and the rest of the ladder will be bypassed.

♦ If none of the conditions are true, the final else statement will be executed.

♦ If there is no final else and all the other conditions are false, then no action will take place.
