SECTION-A (C-Programming)

Q1: Briefly discuss the concept of “Call by value” and “Call by reference”. Give example code in C for each. Support your code with suitable comments.

Q2: Briefly discuss the relation between Pointers and Arrays, giving suitable example. Write a program in C, to print transpose of a 2D matrix entered by a user. Support your program with suitable comments.

Q3: Write an algorithm to find the slope of a line segment whose end point coordinates are (x1, y1) and (x2, y2). The algorithm gives output whether the slope is positive, negative or zero. Transform your algorithm to C program.
Note : Slope of line segment = (y2 – y1) / (x2 – x1)

Q4: Write an algorithm to find the HCF (Highest Common Factor) of the two numbers entered by a user. Transform your algorithm to a C program, support your program with suitable comments.

Q2: What are Pandas ? Write steps to import, read and print a CSV file using Pandas. Also, transform your steps in to suitable code in Python.

Q3: Write steps to create a package. Apply these steps to create a package named volume and create 3 modules in it named cube, cuboid and sphere, having function to calculate volume of the cube, cuboid and sphere respectively. Import the modules defined in the package and use the defined functions for calculation of volume respectively.

Q4: What does map( ) function do ? Write a program in Python to print the cube of the numbers present in the list, by using map( ) function.
