BE Electrical Engineering Semester 2 (FE First Year) - University of Mumbai Important Questions for Structured Programming Approach

What is recursion? WAP using recursion to find the sum of array elements of size n.

what is significance of storage classes? Explain it with relevant examples.

Write a program to multiply two matrices after checking compatibility. 

Write a program to calculate summation of series
1/1! + 2/2! + 3/3! +….+ n/n!

Define union. Compare Structure and Union. 

State True or False with reason.

scanf() function is used to input string having multiple words. 

State True or False with reason.

In a union, space is allocated to every member individually.

State True or False with reason.

There is no difference between ‘\0’ and ‘0’. 

How to create array of structure variable and assign values to its members?

Differentiate between struct and union. When is union preferred over struct? Give on example of each.

Differentiate between structure and union.

Define pointer and its use. Explain array of pointer with example. Write program to swap the values by using call by reference concept. 

Write a program to create two integer of size 8 and 7. Initialize the arrays with random values. Sort the arrays in ascending order with the help of user defined function namely “sort array”. Merge these arrays with the help of another user defined function named “merge arrays” which returns a new array. Program should display the arrays before and after sorting, also the merged arrays.

Write a program to calculate number of vowels (a, e, i, o, u) separately in the entered string.

What are structures? Comment on nested structures. Write a program to read Title, Author and price of 10 books using array of structures. Display the records in ascending order of Price.

Write user defined function to implement string concatenation. 

Write a C program to
i. Create a 2D array [Matrix] [in main function]
ii. Write a function to read 2D array[Matrix]
iii. Write a function that will return true(1) if entered matrix is symmetric or false(0) is not symmetric.
iv. Print whether entered matrix is symmetric or not [in main function]

Implement string copy function STRCOPY (str1,str2) that copies a string str1 (source) to another string str2 (destination) without using library function.

Write a program to sort given array in ascending order. 

Comment on dynamic memory allocation. Write a program to read and store N integers in a Array, where value of N is defined by user. Find minimum and maximum members from the Array.
