A short review if you need: A CRC-3 will have a four-bit polynomial. The largest would be aax + bx² + cx' + dx° . The highest degree is 3, leading to the name CRC-3. The values a b.c.d are coefficients of the terms of each polynomial, and are all single-bit values. A coefficient is either O or 1, thus the term is either included or excluded. We might describe a polynomial by these coefficients. So 1100 (decimal 12, hexadecimal OxC) would be r+ x? Use this polynomial r + x as the generator, with the message 11010111. You should get a 3-bit remainder.

Programming C++ full question: Write a program that prints the multiplication table but inserts a randomly generated incorrect value between 1 and 50 into a cell whose row and column are randomly selected. Make sure the program does insert an incorrect value. For example, if row and column of 3 and 4 are randomly selected, keep generating a random number to print for that location until it's not the right value of 12. Then, ask the user to tell where in the table the incorrect number is located by entering the row and column of the incorrect number. Print whether the user was right or not. If he or she was right, ask for and read the correct value; if not, the program must give the correct location and the correct number. Example:Find the wrong number in the multiplication table below:(the program will print the full table along with a wrong number inserted in it.) 1 2 3 4 5 6 7 8 9 102 4 6 8 10 12 14 16…
6. Given single-character codes for the colored bands that mark a resistor, compute its resistance. The color codes are as follows: Color Code Character Code Black 'B' Brown 'N' 1 bandı Red 2 | banda bands Orange Yellow 3 4 band4 Green Blue 6 Violet Gray White 7 'V' 'A' 9 "W' Figure 1: Resistor Color Bands Table 1: Resistor Color Codes The resistance (2) value of a resistor can be found using the integer value for each color band as follows: R = (bandl * 10 + band2) * 10band3 Write C++ program that finds the resistor value from its color code and output the answer as a numerical format. Remember to use function(s)! P.S.: Use the character code in shown in Table 1 order to represent each color. Sample output Input three color codes: YVO Resistance is: 47000 Ohms.
#Solve it with C programing Suppose, you are working as a Data Entry Operator in a company. You have created a dataset that contains the names of N employees. Then your supervisor wants you to look for a particular employee by name. (Consider, every name in the data set is unique).Now your task is to write a program which will help you to find out the name which your supervisor is looking for.If found then print a message "Matched" otherwise print "Not Matched". (N.B: Without quotation) The first line of input will take an integer (N) which indicates the number of names in the dataset. Then the second line will take N space-separated strings. The third line of input will take another string as search value. Sample input:5rabbe sharif shazzad polash tutulsharif Sample output:Matched Sample input:4jahid nishat rasel shakibmunna Sample output:Not Matched

Primary U.S. interstate highways are numbered 1-99. • Odd numbers (like the 5 or 95) go north/south, and even numbers (like the 10 or 90) go east/west. • Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, 1-405 services 1-5, and 1-290 services 1-90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also, indicate if the (primary) highway runs north/south or east/west. Use the information above to write several functions to help you determine this information. Call these functions in your main program to produce the requested output. Instructions The functions Write a function get_direction () that expects a highway number. • Returns a string "north/south" if the highway number is odd (like the 5 or 95); • Returns "east/west" if the highway number is even (like the 10 or 90). If the function is called with the following input 290 the…

In this lab, you will determine the least common multiple (LCM) of two numbers in memory named datax and datay. The calculated LCM value should be stored in the area of memory directly following the given data. To calculate the LCM, you can first find the greatest common divisor (GCD) of the two numbers and use the formula LCM(xy)*GCD(x,y) = x*y. To find the GCD, you can use Dijkstra's Algorithm to forgo the use of division or modulus functions. Pseudocode (C code) for Dijkstra's Algorithm used to find the GCD is as follows: int GCD(int x, int y) { if(x == y) return x; else if(x > y) return gcd(x-y, y); else return gcd(x, y-x); } Notice that you are passing values in and out of subroutines, which is the focus of lecture this week. You may choose any of the 3 methods (pass by registers, reference, or stack) that you feel is most appropriate.
