OBJECTIVES:
• To develop programs in C using basic constructs.
• To develop applications in C using arrays and functions.
• To develop applications in C using Strings and Structures.

List of Programs

1. Programs using I/O statements and expressions.
2. Programs using decision-making constructs.
3. Write a program to find whether the given year is leap year or Not? (Hint: not
everycenturion year is a leap. For example 1700, 1800 and 1900 is not a leap year)
4. Write a program to perform the Calculator operations, namely, addition, subtraction,
multiplication, division and square of a number.
5. Check whether a given number is Armstrong number or not?
6. Check whether a given number is odd or even?
7. Write a program to perform factorial of a number.
8. Write a C program to find out the average of 4 integers.
9. Show how to display array elements using two dimensional array.
10. Write a C program to perform swapping using function.
11. Display all prime numbers between two intervals using functions.
12. Reverse a sentence using recursion.
13. Write a program in C to get the largest element of an array using the function.
14. Write a C program to concatenate two string.
15. Write a C program to find the length of String.
16. Find the frequency of a character in a string.
17. Write a C program to Store Student Information in Structure and Display it.
18. The annual examination is conducted for 10 students for five subjects. Write a program to
read the data and determine the following:
(a) Total marks obtained by each student.
(b) The highest marks in each subject and the marks of the student who secured it.
(c) The student who obtained the highest total marks.


TOTAL: 60 PERIODS

COURSE OUTCOMES:

Upon completion of the course, the students will be able to

• Develop C programs for simple applications making use of basic constructs, arrays and strings.
• Develop C programs involving functions, recursion, pointers, and structures.
• Design applications using sequential and random access file processing.

PROGRAM
/*
* Sum the odd and even numbers, respectively, from 1 to a given upperbound.
* Also compute the absolute difference.
* (SumOddEven.c)
*/
#include <stdio.h> // Needed to use IO functions
int main()
{
int sumOdd = 0; // For accumulating odd numbers, init to 0
int sumEven = 0; // For accumulating even numbers, init to 0
int upperbound; // Sum from 1 to this upperbound
int absDiff; // The absolute difference between the two sums
int number = 1;
// Prompt user for an upperbound
printf("Enter the upper bound: ");
scanf("%d", &upperbound); // Use %d to read an int
// Use a while-loop to repeatedly add 1, 2, 3,..., to the upperbound
