1. a) Write a C++ program to create a file stcok.dat and save the details of stock
such as item name, item code and item price. Calculate the area of a sphere, rectangle and triangle using a single function named area. Use the function verloading concept of C++. Run the program and show the result for the given input values.
b) Compute the y-coordinates of a straight line with slope equal to 0.5 and intercept equal to - 2, using MATLAB at the following x values x = 0, 1.5, 3.0, 4, 5, 7, 9, 10.
2. a) Write a C++ program to perform arithmetic operations on two complex numbers
using the concept of class.
b) Use MATLAB to draw a straight line with slope 0.3 and intercept = 5, choosing values of x-coordinate as [0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50]
3. a) Write a menu driven program for performing basic banking operations using
concept of class.
b) Using Matlab create a vector t with 15 elements : 2, 4, 6, 8,........., 30 and
compute :
t -1 Sin(t2)
a) y b)
Z :
2
t + 1 t
4. a) Write a program in C++ to overload the operator for scalar multiplication of a vector.
b) The sum of a geometric series 1 + r + r2 +r3 +.........+ rn approaches the limit.
1
-for r < 1 as n . By creating vector n of 101 elements from 0 to 100
1 - r
and r as 0.5, find the sum of the geometric series using sum command in Matlab.
1
Also calculate the limit-manually and compare the computed sum.
1-r
5. a) Write a program in C++ to sort a given string.
b) Plot y = sin x, 0 < x < 2 n, using Matlab taking 100 linearly spaced points in the given interval. Label the axis and put Plot created by your candiate code in the title.
6. a) Write a program to multiply two matrices.
b) Write a function file in Matalab to plot a graph of y = e-0 4x sin x, 0 < x < 4 n taking 50 points in the interval.
7. a) Write a program in C++ to search for a given element in an array and display its
position.
b) For any integer n, write a function factorial in MATLAB to compute n!.
8. a) Write a program in C++ to swap two numbers using call by reference method
b) Write a function in Matlab that outputs a conversion table for Celsius and Fahrenheit temperatures. The input of the function should be two numbers T and Tf, specifying the lower and upper range of the table in Celsius. The output should be a two column matrix : the first column showing the temperature in Celsius from T to Tf in the increments of 1C and the second column showing the corresponding temperature in Fahrenheit.
