Write in C Language Frequent Letter Your Facebook account has just been hacked and you want to change its password. To create a strongpassword, Facebook just recommended you two strings S and T, each contains N lowercase English letters. You want to choose a password containing N lowercase English letters such that the i th character is either the i th character of S or the i th character of T. For example, if S = icyz and T = ixpc, then there are 8 different passwords that you can choose: icyz, icyc, icpz, icpc, ixyz, ixyc, ixpz, ixpc. The strength of your password is defined as the number of occurences of the most frequent letter. For example, the strength of icyz is 1 and the strength icpc is 2. You are wondering what is the strength of the strongest password that you can choose.
4: In the Department of Mathematics and Computer Science (MACS), undergraduate course codes begin with either M (for Mathematics courses) or CS (for Computer Science courses). Thereafter, the code has four (4) digits. The first digit is the year of study, which is 1 to 6. The second digit is the credit hours, which is again 1 to 5. For Mathematics courses, the third and the fourth digits is just a running index to differentiate the course from the others. For Computer Science courses, the third digit is the area of specialisation, which is from 0 to 4. The fourth and the last digit is just a running index to differentiate the course from the others. a) Draw a finite state machine (FSM) accepting/generating course codes in MACS. b) As the result of a) above, write the corresponding C++ function int is_MACS_course(char * str) { I/ C++ code which will determine whether or not the given string, str, represents the correct code for MACS courses.

C++ Language Write a program that prints a custom conversion table from Celsius temperatures to Fahrenheit and Newton (Links to an external site.) temperatures. The formula for the conversion from Celsius to Fahrenheit is : F=9/5*C+32 F is the Fahrenheit temperature, and C is the Celsius temperature. The formula for the conversion from Celsius to Newton is C = 100/33*N N is the Newton Temperature and C is the Celsius temperature Your program should prompt the user for a lower value and upper value for a range of temperatures in Celsius. It should then prompt the user for the amount they want to increment by. Then use a loop to output to a file named conversion_table.txt a table of the Celsius temperatures and their Fahrenheit and Newton equivalents within the range of values using the increment given by the user. Make sure to format your output to 2 decimal places. INPUT VALIDATION: Ensure the second number is greater than the first number, and make sure the increment is greater…
