Q1 Write a C program that inputs the total selling price of 8 Toyota Corolla cars and the total
profit earned on them. The program finds and prints the manufacturing price of three of these
cars.
Sample Output:
Input the total selling price of eight Corolla cars in OMR: 65900.98
Input the total profit on eight Corolla cars in OMR: 15785.78
The manufacturing price of three Corolla cars in OMR is: 18793.2

Q2 Write a C program to enter 3 letters and find the largest and smallest letters and display them.
If the difference between the largest and smallest letter is more than 10, the program
increments the smallest letter by 1, otherwise it decrements the largest letter by 1.
Note: Only conditional operator must be used (no if else).
Sample Output:
Enter 3 letters: z r b
The smallest letter is: b
The largest letter is : z
The smallest and largest letters after updating: c z

Q3 Write a C program that inputs 4 integers A, B, C and D (as 0 or 1). The program calculates
and prints the values of N and M from the following logical equations:
N= A.C.D.(B.C+A)
M= B.A+C.D.B
Hint: In logical equations the symbol ( . ) represents AND logical operation, ( + ) represents
OR logical operation and ( ) represent NOT logical operation.
Sample Output:
Input A, B, C, D as 1 , 0: 1 0 1 1
N= 0
M= 1

Q4 Write a C program to input two five digit numbers n1 and n2. From the first number, extract
the first 3 digits and from the second number extract the last three digits and print the new
numbers. Find the maximum of the two new numbers and print the result. Then find the
difference between this maximum number and the greatest possible 3-digit number and print
the result. Also find and display by how much this maximum number is greater than the
smallest possible 3-digit number.
Sample Output:
Enter two five digit numbers: 12345 10234
The two new numbers are 123 234
The maximum is 234
Difference of the maximum number from the greatest 3-digit number:765
Difference of the maximum number from the smallest 3-digit number :134

Q5 A bank allows maximum of 30 transactions for a customer in a month. Write a C program to
input the bank balance of customer (bal) at the start of the current month, total number of
transactions (t) in the current month, total transactions amount (amt) in the current month
and an integer choice (ch). According to the input choice, the program performs one of the
following operations as shown in the table below.
Value of ch Operation
1 Finding the remaining balance and displaying it. If the remaining
balance is less than 100 OMR, displaying a warning message ”low
balance”
2 Finding the average amount of transactions performed in this month
and displaying it.
3 Finding the number of transactions remaining for the month and
displaying it.
Any other
number
Display “wrong choice”
Sample input output- 1:
Input the bank balance, no. of transactions and amount transferred: 2000 4 1920
Enter the choice: 1
New balance is 80.0 OMR
Low balance
Sample input output- 2:
Input the bank balance, no. of transactions and amount transferred: 2000 4 1920
Enter the choice: 2
Average transaction amount is: 480.0000
Sample input output- 3:
Input the bank balance, no. of transactions and amount transferred: 2000 4 1920
Enter the choice: 3
Remaining transactions for the month: 26

Q6 Write a C programusing else if statement to input one letter by the user and input three real
numbers x, k and n. Then the program performs one of the following operations based on the
input letter and prints its result as shown in the following table.
Letter Operation
From A to H 𝑦 =
𝑘. 𝑥
𝑛 + 5

𝑥
𝑘. 𝑛
From I to M
y = 8×3 + 20x -100
From N to Z
𝑦 = 12𝑥

Q7 Draw the flowchart and write a C program using else if to calculate the salary of a person
according to the following conditions:
Input the basic salary and designation code. Based on both basic salary and designation
code, calculate the total salary.
Total salary= basic salary+ HRA+ DA+ TA+ phone allowance

Q8 Draw the flowchart and write a C program using switch. The program inputs one character
selector and three integer numbers. Depending on the selector the program performs some
operations on the integer numbers and display the output. [4+5]
Selector Operations on integer numbers
S or s Displaying the sum of the squares of the numbers.
A or a Displaying the average of the numbers.
E or e Displaying the sum of even numbers and their count.
Other characters Wrong Selector
Sample output 1:
Input a character selector : S
Input 3 integers: 14 7 -4
Sum of square of these numbers=261
Sample output 2:
Input a character selector : a
Input 3 integers: 14 7 -4
Average of numbers= 5.666667
Sample output 3:
Input a character selector : E
Input 3 integers: 14 7 -4
Sum of even numbers =10
Count of even numbers=2
Sample output 4:
Input a character selector : K
Input 3 integers: 14 7 -4
Wrong Selector
