Q3: Write a C++ program to Find All Roots of a Quadratic Equation.

Q2: Write a C++ program to check if given integer is even or odd.

Write a FOR loop (just the loop) in C++ to print out the following sequence of numbers: 5 10 15 20 25 30 35 40 45 50

Pascal's Triangle: The example output of this program shows a pascal's triangle. To build the pascals triangle, start with 1 at the top, then continue placing numbers below it in a triangular pattern. Each number is the numbers directly above is added together. Explore this link for hints of pascal's triangle: https://www.mathsisfun.com/pascals-triangle.html 3.a): Write a C++ program to print the pascal's triangle by using “for loop". The program should take the number of rows as input from the user. The output of the program should be as in the following pattern (e.g., if you enter the number of rows = 8). Note: specific grading criteria: You need to use only for loop and print a well-designed pattern. The output mentioned below is just an example; more clear and well-presented output will improve your marks. (10 marks). Example Output: Enter the number of rows: 8 1 1 1 1 2 1 13 3 1 1 4 6 4 1 15 10 10 5 1 16 15 20 15 6 1 1 7 21 35 35 21 7 1
