- Write a program in C++ that repeatedly prompts the user to enter a capital for a state. Upon receiving the user input, the program reports whether the answer is correct. A sample run is shown below: What is the capital of Alabama? Montgomery [ENTER]Your answer is correct.What is the capital of Alaska? Anchorage [ENTER]The capital of Alaska is Juneau Assume that fifty states and their capitals are stored in a two-dimensional array, see below. The program prompts the user to enter ten states’ capitals and displays the total correct count.arrow_forwardwrite a c++ program that declares an array that can hold 20 chars. then the program outputs two upper case character which are A & Z(initials). next using a loop the program populates the array with the pair of the initials until the array is full. then the program outputs the array on one line. then the program swaps the contents of the first and last locations in the array and output the modified array on the next line.arrow_forwarda. Write a program that reads your id and full name and display. And also display the index of first letter and last letter of your full name. b. Modify above program, Declare a string course, let your program read course from user, check if course is not equal to comp2002, clear the string otherwise concatenate course and " Computer Science Department". C. Modify above program declare a string college="". If string college is empty then assign a new string "College of Science".arrow_forward
- This program involves inputting multiple data items (temperatures) that are each within a certain range and then outputting a report about them utilizing arrays and methods. 1. The program will input from 1 to 35 (inclusive) Fahrenheit temperatures from the user. You must first ask them to enter the number of temperatures that they will be typing in. If the value entered is not between 1 and 35, you need to display a message informing the user that the value they entered is out of range and make them re-input until they provide an acceptable value. Prompt every input. 2. The Fahrenheit values are doubles and must range between -150.0 and 350.0 (inclusive.) If an out-of-range temperature is entered, you must display a message informing the user as such and have them re-input until an in-range value is entered. 3. Generate the output specified below. Notes/Specifications: 1. You must create an array to hold your (double) temperature values. 2. All output needs to be right-justified and…arrow_forwardSuppose a teacher has five students who have taken four tests. The teacher uses the following grading scales to assign a letter grade to a student, based on the average of his or her four test scores. Test Score Letter Grade 90-100 80-89 70-79 60-69 0-59 A B C D F Create an application that uses an array of strings to hold the five student names, an array of five strings to hold each student's letter grades, and five arrays of four single precision numbers to hold each student's set of test scores.arrow_forwardI need to write a program named Search.java that uses a function called search_string to check whether a string exists in the array or not. 1- The array of strings is iterated using a for loop and the value at every index is compared with the value to be searched in the array. 2- A boolean variable is set if any array value matches with the string. 3- At the end of the loop, this boolean variable is checked to determine if the array contains the string. It may be necessary to import java.util.Arrays then use Arrays.toString, String equals(). Output should be as picture showsarrow_forward
