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
