- Please solve using C++ program step by step code and a screenshot for the output of the program 3. Something went horribly wrong with the encrypted document backup process at the college and all files were converted to strings containing 1’s and 0’s representing the binary representation of the file. Write a program to restore all the files. All the original files were in 16-bit Unicode. Input from a text file containing a long string of 1’s and 0’s whose length is guaranteed to be a multiple of 16. Output to the screen the original file contents. Let the user input the file name from the keyboard. Refer to the sample output below.

- In c++ Now write a program for a double floating pointtype.•What are the number of significant bits that the double’s mantissa can hold, excluding the sign bit.•What is the largest number that a double’s mantissa can hold without roundoff error?•Repeat the program shown on the previous page but set to show where the double’s mantissa starts to exhibit roundoff errors.Write a program in C++ to find the Greatest Common Divisor (GCD) of two numbers iteratively.Sample Output:Input the first number: 12Input the second number: 8The Greatest Common Divisor is: 4A program in the C language that receives from the user an actual number up to 3 digits after the dot, It can be assumed that the number does not contain more than 3 digits after the dot. The program will separate it into a whole and an actual part. The number should be printed as an integer followed by a fraction, Pay attention to the accuracy of the actual numbers to handle a situation where there is an inaccuracy (like 2.3 Which appears as 2.299). Note: The MODF function must not be used, The things that are only allowed to be used are Types, operators and conditions, For example: The number 3.532 will be printed: 3 532/ 1000 The number 43.75 will be printed: 43 75/ 100 The number 84.5 will be printed: 84 5/ 10 The number 2.3 will be printed: 2 3/ 10 The number 85 will be printed: 85 0/ 10 The number 33 will be printed: 33 0/ 10
- Write a C program that adds two very large integers entered by the user on the keyboard. You cannot sum very large integers using standard data types (long int, double, etc.). You have to read the numbers as a string on the keyboard and perform the addition process by adding the mutual numbers one by one, starting from the ones digit as you learned in elementary school. Your program should also work in case the numbers entered by the user have different numbers. The output of your program should be compatible with the sample program outputs below. In the output of the program, the numbers and the total should be written one after the other, in line with the mutual digits as in the addition process.Write a C program that reads two matrices of integers. It then generates the sum and difference of the two matrices. The sum of the two matrices of the same size is a matrix with elements that are the sums of the corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes. If A and B are matrices of the same size, then we define subtraction as follows: A – B = A + (-B). Thus, to subtract matrix B from matrix A, we simply subtract corresponding elements.Using C language. Write a program that reads two matrices of integers. It then generates the sum, difference and product of the two matrices. The sum of the two matrices of the same size is a matrix with elements that are the sums of the corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes. If A and B are matrices of the same size, then we define subtraction as follows: A - B = A + (-B). Thus, to subtract matrix B from matrix A, we simply subtract corresponding elements. To multiply a matrix by another matrix we need to do the "dot product" of rows and columns. The "Dot Product" is where we multiply matching members, then sum up: (1, 2, 3) • (7, 9, 11) = 1×7 + 2x9 + 3x11 = 58 We match the 1st members (1 and 7), multiply them, likewise for the 2nd members (2 and 9) and the 3rd members (3 and 11), and finally sum them up.
- Please Answer in C++ language only Today the chef decided to cook some tasty dishes from the ingredients in his kitchen. There is an NN of components, represented by the strings S1,S2, .... SN. The chef took all the ingredients, put them in a cauldron and mixed them. In the cauldron, the letters of the strings representing the ingredients are completely shuffled, so that each letter appears in the cauldron as many times as it has appeared in all the strings combined; now the cook can take out one letter from the cauldron at will (if that letter appears in the cauldron more than once, it can be taken out that many times) and use it in a dish. Complete Food is a "chef" chain. Help the chef find the maximum number of complete meals he can make! Input 1 5 codechef chefcode fehcedoc cceeohfd codechef Output 5Solve the below program in C language. Write a program in C to print all perfect numbers in given range using the function. Test Data :Input lowest search limit of perfect numbers : 1Input lowest search limit of perfect numbers : 100Expected Output : The perfect numbers between 1 to 100 are : 6 28For this assignment, you must implement the ElGamal Public-Key Encryption scheme with any programming language that you are comfortable with. The recommendation is to use C/C++ or Java. You can accomplish this assignment individually or by forming a team of 2 students. Alternatively, you can work with your team members of the previous assignment. Your program should get the "key size" from the user in terms of number of bits (for instance, 64, 128, etc). Based on the size, use Fermat or Miller-Rabin primality test algorithm to define your large prime number. You can use the existing programming packages to find a generator of your finite field. Your program should then initialize a pair of key, i.e., private and public keys. For the computations, utilize the Square-and Multiply algorithm. In fact, your program should get a plaintext from the user to perform encryption (generating the ciphertext from the plaintext) and decryption (generating the original plaintext from the ciphertext).…
