Exercise
l
a)
Write a C Program to calculate the area of triangle using the formula area
= (
s (s-a) (s-b)(s-c))1/2 where s= (a+b+c)/2
b)
Write a C program to find the largest of three numbers using ternary operator.
c)
Write a C Program to swap two numbers without using a temporary variable.
Exercise
2
a) 2’s complement of a number is obtained by
scanning it from right to left and complementing all the bits after the first
appearance of a 1. Thus 2’s complement of 11100 is
00100. Write a C program to find the 2’s
complement of a binary number.
b) Write a C program to find the roots of
a quadratic equation.
c) Write a C program, which takes two
integer operands and one operator form the user, performs the operation and
then prints the result. (Consider the operators +,-,*, /, % and use Switch
Statement)
Exercise 3
a) Write a C program to find the sum of
individual digits of a positive integer and find the reverse of the given
number.
b) A Fibonacci sequence is defined as
follows: the first and second terms in the sequence are 0 and 1. Subsequent
terms are found by adding the preceding two terms in the sequence. Write a C program
to generate the first n terms of the sequenceUse the summing series method to
compute the value of SIN(x),COS(x) and e x.
c) Write a C program to generate all the
prime numbers between 1 and n, where n is a value supplied by the user.
Exercise 4
a) Write a C Program to print the
multiplication table of a given number n up to a given value, where n is
entered by the user.
b) Write a C Program to enter a decimal
number, and calculate and display the binary equivalent of that number.
c) Write a C Program to check whether the
given number is Armstrong number or not.
Exercise 5
a) Write a C program to interchange the
largest and smallest numbers in the array.
b) Write a C program to implement a liner
search.
c) Write a C program to implement binary
search
Exercise 6
a) Write a C program to implement sorting of
an array of elements .
b) Write a C program to input two m x n
matrices, check the compatibility and perform addition and multiplication of
them

string from a given position.
ii. To delete n Characters from a given
position in a given string.
iii. To
replace a character of string either from beginning or ending or at a specified
location
