www.dataidea.org- Write a program to assign the number 34.5678 to a variable named “number” then display the number rounded to the nearest integer value and next the number rounded to two decimal places.
# your solution- Write a program to identify whether a number input from the keyboard is even or odd. If it is even, the program should display the message “Number is even”, else it should display “Number is odd”.
# your solution- Write a program to display the student’s grade based on the following table:
| Marks | Grade |
|---|---|
| >= 75 | A |
| > 50 and <=75 | B |
| > 25 and <=50 | C |
| <= 25 | D |
# your solution- Write a program to convert a given character from uppercase to lowercase and vice versa.
# your solution- Write a program which accepts a number (an amount of money to be paid by a customer in rupees) entered from the keyboard. If the amount is greater than or equal to 1000 rupees, a 5% discount is given to the customer. Then display the final amount that the customer has to pay.
# your solution- A car increases it velocity from u ms-1 to v ms-1 within t seconds. Write a program to calculate the acceleration.
# your solution- Write a program to input a temperature reading in either Celsius(c) or Fahrenheit(f) scale and convert it to the other scale. The temperature reading consists of a decimal number followed by letter ”F” or ”f” if the temperature is in Fahrenheit scale or letter ”C” or ”c” if it is in Celsius scale. You may use a similar format for the output of the program. Note:
c = 5( f − 32) / 9
# your solution- Develop a simple calculator to accept two floating point numbers from the keyboard. Then display a menu to the user and let him/her select a mathematical operation to be performed on those two numbers. Then display the answer. A sample run of you program should be similar to the following:
Enter number 1: 20
Enter number 2: 12

# your solution- Write a program to calculate the factorial of any given positive integer.
# your solution- Write a program to compute the sum of all integers between any given two numbers. In this program both inputs should be given from the keyboard.
# your solution- What would happen if we enter -1 as the number of times to loop in Program-5.4? Modify Program-5.4 so that it works only for positive integers.
# your solution- Write a program to display the following symbol pattern:
*
**
***
****

Enter number of your preference:# your solution- Develop a simple telephone directory which saves your friends contact information in a file named directory.txt. The program should have a menu similar to the following:
----------------Menu-------------------------
1. Add new friend.
2. Display contact info.
3. Exit
------------------------------------------------
Enter menu number:When you press “1” it should request you to enter following data:
---------New friend info--------
Name : Saman
Phone-No: 011-2123456
e-Mail : saman@cse.mrt.ac.lkAfter adding new contact information it should again display the menu. When you press “2” it should display all the contact information stored in the directory.txt file as follows:
--------------Contact info---------------

-----------------------------------------# your solution- Given a date as a triplet of numbers (y, m, d), with y indicating the year, m the month (m = 1 for January, m = 2 for February, etc.), and d the day of the month, the corresponding day of the week f (f = 0 for Sunday, f = 1 for Monday, etc.) can be found as follows:
(a) if m < 3
(b) let m = m + 12 and let y = y - 1
(c) let a = 2m + 6 (m + 1) / 10
(d) let b = y + y/4 – y/100 + y/400
(e) let f 1 = d + a + b + 1
(t) let f = f 1 mod 7
(g) stop.Write a program that will read a date and print the corresponding day of the week. All divisions indicated above are integer divisions.
# your solution- Write a program to input a series of positive integers and determine whether they are prime. The program should terminate if a negative integer is given as the input. A prime number is a number that is divisible by only one and itself. However one is not considered a prime number.
# your solution- Write a program to find out whether a given number is a perfect number. The program should terminate if a negative integer is given as the input. A perfect number is a number whose factors other than itself add up to itself.
# your solution- Write a program to find and display the minimum and the maximum among 10 numbers entered from the keyboard. Use a single-dimensional array to store the numbers entered. The numbers can be non-integers. An example would be as follows:
Enter 10 numbers: 5 7.8 9.6 54 3.4 1.2 3 7 8.8 5
Minimum = 1.2
Maximum = 54# your solution- Suppose there are 4 students each having marks of 3 subjects. Write a program to read the marks from the keyboard and calculate and display the total marks of each student. Use a 2D (two-dimensional) array to store the marks. An example would be as follows:
Enter the marks of four students, on four rows:
50 60 80
60 75 90
30 49 99
66 58 67
Total marks of four students:
190
225
178
191# your solution- Write a program to read in two matrices A and B of dimensions 3×4 and 4×3 respectively, and compute and display their product AB (of dimensions 3×3). Assume that the elements of the matrices are integers. Use functions to while implementing this program.
