DSC01: Programming using C++

Theory Assignment - 1

1. Write a program in C++ to input a two-digit number and print its reverse.
2. Write a program in C++ to input a two-digit number and print the sum of its digits.
3. Write a program in C++ to find the third angle of a triangle.
4. Write a program in C++ to enter values of principal amount, rate of interest and time and calculate- a) simple interest and b) compound interest.
[Hint: Include math.h file and use pow() function.]
5. Write a program in C++ to find roots of a quadratic equation.
[Hint: Include math.h file and use sqrt() function.]
6. Write a program in C++ to swap the values of two integer variables- a) using a third variable
and b) without using a third variable.
7. Write a program in C++ to check whether a number is positive, negative or zero.
8. Write a program in C++ that asks the user to input lengths of three sides and angles of a triangle and-
i) prints whether it is a valid triangle or not
ii)if the triangle is valid, prints whether the triangle is equilateral, scalene or isosceles
9.Write a program in C++ that accepts a character and-
i) prints whether the character is a letter or a numeric digit or a special character
ii) if the character is a letter, prints whether the letter is upper case or lower case 
10. Write a program in C++ having a user defined function that repeatedly asks for numbers until the user provides a negative number.
11. Write a program in C++ having a user defined function that accepts an integer argument and
returns a Boolean value. The function should return true if the integer argument is greater than or equal to zero, and false otherwise. Call this function with a positive and negative value to test that it works, and display the result.
