Programming & Computer Science Answers

1. Write a C program using an online C compiler that implements the following:-

• Declare a floating-point variable (of type float)

• Declare an integer variable (of type int)

• Prompt the user to enter a floating-point number.

• Read a number from the keyboard into your floating-point variable

• Using casting, write the contents of your floating-point variable into your integer variable • Display the value of your integer variable.

·     High level of redundancy is expected in network design to eliminate single point of failures and traffic bottle necks.

·     Sales and Marketing Team need to access Network resources using WIFI connectivity.

·     Proper methods for networking monitoring and troubleshooting need to be established.

·     All possible network security mechanisms should be implemented.

·             Discuss the importance and impact of network topologies and network protocol suites while comparing the main network topologies and network protocol suites that are used in network design using examples. Recommend suitable network topologies and network protocol suites for above scenario and justify your answer with valid points.

Write a program For example, if the given numbers are M is 4 and N is 16, the perfect squares from 4 to 16 are 4(2 * 2), 9(3 * 3), and 16(4 * 4), as the first perfect square is 4. So the output should be 4.

Else print No perfect Square

Add two polynomials

Given two polynomials A and B, write a program that adds the given two polynomials A and B.

Input

The first line contains a single integer M.

Next M lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes co-efficient of Pi for polynomial A.

After that next line contains a single integer N.

Next N lines contain two integers Pj, Cj separated with space, where Pj denotes power and Cj denotes co-efficient of Pj for polynomial B.

Output

Explanation

If M = 4 and for polynomial A

For power 0, co-efficient is 5

For power 1, co-efficient is 0

For power 2, co-efficient is 10

For power 3, co-efficient is 6.

If N = 3 and for polynomial B

For power 0, co-efficient is 1

For power 1, co-efficient is 2

For power 2, co-efficient is 4.

Then polynomial A represents "6x^3 + 10x^2 + 5", the polynomial B represents "4x^2 + 2x + 1" and the addition of A and B is "6x^3 + 14x^2 + 2x + 6"

1. In the following program, what would be the final output? Explain in

detail.

void copyarr( char ∗p1 , char p2 [ ] ) {

memcpy ( p2 , p1 , size of ( p1 ) ) ;

memcpy ( p2 , ‘ ‘ABCD’ ’ , 4 ) ;

}

int main ( ) {

char arr1 [ 100 ] ;

char arr2 [ 100 ] ;

printf( ‘ ‘ Enter a string : ’ ’ ) ;

scanf ( ‘ ‘%[ ˆ\n ] s ’ ’ , arr1 ) ;

copyarr ( arr1 , arr2 ) ;

printf ( ‘ ‘ \ n %s ’ ’ , arr2 ) ;

return 0 ;

}

Write a program that allows any number of values between 0 and 10 to be entered. When the user stops entering values, display a frequency distribution bar chart. Use asterisks to show the number of times each value was entered. If a given number is not entered, no asterisks should appear on that line. Your application should display error messages if a value outside the acceptable range is entered or if a non-numeric character is entered.

Write a program that reads data into an array of type int. Valid values are from 0 to 10. Your program should display how many were inputted as well as the number of invalid entries. Output a list of distinct valid entries and a count of how many times that use the following test data

1 7 2 4 2 3 8 4 6 4 4 7

Write a program to enter the numbers till the user wants and at the end it should display the

count of even, odd and prime numbers entered.
