Can you please do it using the language Java not c++. Please
- 3.27 LAB: Login name Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first six letters of the first name, followed by the first letter of the last name, an underscore (_), and then the last digit of the number (use the % operator). If the first name has less than six letters, then use all letters of the first name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: MichaeJ_1 Ex: If the input is: Nicole Smith 2024 the output is: Your login name: NicoleS_43. Write a code for craps game. Craps is a dice game in which the players make wagers on the outcome of the roll, or a series of rolls, of a pair of dice.The rules of the dice game craps are as follows:You roll two dice. Each die has six faces, which contain one, two, three, four, five and six spots, respectively. After the dice have come to rest, the sum of the spots on the two upward faces is calculated. If the sum is 7 or 11 on the first throw, you win and play is over. If the sum is 2, 3 or 12 on the first throw you lose and play is over. If the sum is 4, 5, 6, 8, 9 or 10 on the first throw, that sum becomes your “point.” To win, you must continue rolling the dice until you “make your point” (i.e., roll that same point value). You lose by rolling a 7 before making your point. 4. Write a program which prompts the user for their age. If they are 19 or younger inform them that qualify for student discounts. If they are between 20 and 65 inform them that they qualify for no age…1. Examine the following code segment. What will be printed?If there are any errors indicate the nature of each error.int a[7] = { 31, 12, 32, 14, 25, 16, 27 };int *ptr ;ptr = & a[ 2 ] ;for( i = 1; i <= 5; i = i + 2)cout << *( ptr + i ) ;cout << a[0] << *ptr << *ptr - 2 << *(ptr - 1)) << endl;
- 1. Examine the following code segment. What will be printed?If there are any errors indicate the nature of the error. int a[8] ={16, 12, 10, 7, 15, 18, 17, 29}; int *ptr ; ptr = & a[ 5 ] ; for(int i = 0; i<= 4; i = i + 2) cout<<a[i]<<*( ptr + i )<<endl; cout<<” ”<<a[1]<<” ”<<*ptr<<” ”<<*ptr + 2<<” ”<<*(ptr + 3);10. Examine the following code segment. What will be printed? If there are any errors indicate the nature of the error. int a[9] = { 1, 12, 3, 14, 25, 16, 7, 8, 9 }; int *ptr ; ptr = & a[ 2 ] ; for( i = 1; i <= 5; i = i + 2) cout << a[i] << *( ptr + i ); cout << ” ” << a[0] << ” ” << *ptr << ” ” << *ptr - 1 << ” ” << *(ptr - 2));17.54 PRACTICE: Functions***: Output guitar tabs C++ An earlier problem introduced guitar tabs. In this problem, the user can enter a sequence of chords, and the program should output the tabs in sequence. The first input is the number of chords to follow. If the input is 4 G C G D, the output should be: e|-3-0-3-2- B|-0-1-0-3- G|-0-0-0-2- D|-0-2-0-0- A|-2-3-2--- E|-3---3--- Hints: Use 6 C++ strings, one for each guitar string ("string" below will mean C++ string unless otherwise noted). Start by the e string with "e|-", the B string with "B|-", etc. For each user chord, append (using append()) to each string the appropriate item (a number or -) plus -, like "2-". When done, print the 6 strings one at a time separated by newlines.
- 19.12 LAB: Convert from seconds People find it easier to read time in seconds, minutes, and hours rather than just seconds. Write a program that reads in seconds as input, and outputs the time in seconds, minutes, and hours. Ex: If the input is: 4000 the output is: Seconds: 40 Minutes: 6 Hours: 1 #include <iostream>using namespace std; int main() { int seconds; int minutes; int hours; /* Type your code here. */ return 0;}6.6 In Python, Many documents use a specific format for a person's name. Write a program whose input is: firstName middleName lastName and whose output is: lastName, firstInitial.middleInitial. Ex: If the input is: Pat Silly Doe the output is: Doe, P.S. If the input has the form: firstName lastName the output is: lastName, firstInitial. Ex: If the input is: Julia Clark the output is: Clark, J.(7) Implement the ShortenSpace() function. ShortenSpace() has a string parameter and updates the string by replacing all sequences of 2 or more spaces with a single space. ShortenSpace() DOES NOT output the string. Call ShortenSpace() in the PrintMenu() function, and then output the edited string. Ex: Edited text: We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue!
- 6.26 LAB: Exact change - functions Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies. def exact_change(user_total) Use Python, please.17.49 Lab: Functions: Number to words Sometimes numbers are converted to words, like in a wedding invitation. So 23 becomes "twenty three". Write a function DigitToWord that takes a single digit number from 0-9 and returns that number's word: 0 is zero, 1 is one, 2 is two, etc (if the number is outside 0-9, return "error"). Write another function TensDigitToWord that takes a single digit number from 2-9, and returns that number's word when it appears in the tens digit: 2 is twenty, 3 is thirty, etc. If the number is outside 2-9, return "error". Finally, write a function TwoDigitNumToWords that takes a two-digit number from 20-99 and returns that number in words. Your main program should get a user's integer, call TwoDigitNumToWords, and output the resulting string. If the input is 23, the output should be "twenty three". Do not do any error checking of the input. Note that your program does not support all numbers. 0-19 will yield error output, for example. HINTS: Write…10 - In an examination, 500 students appeared. Out of these students, 38 % got A+ grade, 45 % got B+ and the remaining just passed. Assuming that no student failed, find the number of students who got A+, B+ and the number of students who just passed.(Python code)
