Here's a C++ code example for your question:n```cppn#include <iostream>n#include <vector>nnconst int NUM_SEATS = 5;nstd::vector<char> seats(NUM_SEATS, 'A'); // 'A' denotes available seatnnvoid displaySeats() {n for (int i = 0; i < NUM_SEATS; ++i) {n std::cout << "Seat " << i+1 << ": " << seats[i] << "
"; n }n}nnvoid reserveSeat(int seatNum) {n if (seats[seatNum-1] != 'R') {n if (seats[seatNum-1] == 'A') {n seats[seatNum-1] = 'R'; n std::cout << "Seat " << seatNum << " reserved
"; n } else {n std::cout << "Error: Seat " << seatNum << " is already reserved
"; n }n } else {n std::cout << "Error: Seat out of range (1-" << NUM_SEATS << ")
"; n }n}nnint main() {n while (true) {n displaySeats();n int seatNum;n std::cout << "Enter seat no. (Press 0 to terminate): " << std::endl;n std::cin >> seatNum;n if (seatNum == 0) {n break;n } else if (seatNum > 0 && seatNum <= NUM_SEATS) {n reserveSeat(seatNum);n }n }n return 0;n}n```

Is the following statement a declaration/definition. Find what does it mean? int (*x)[10];

1) int i=5; j=i++ + i++ + i++; printf("%d",j);This code gives the answer 15.But if we replace the value of the j then anser is different?why? 2)int i=5; printf("%d",i++ + i++ + i++); this givs 18.

3) Int Matrix of certain size was given, We had few valu= es in it like this. =97=97=97=97=97=97=97=97=97=97=97 1 = | 4 | | 5 | &= nbsp; | 45 =97=97=97=97=97=97=97=97=97=97=97 &n= bsp; | 3 | 3 | 5 | = | 4 =97=97=97=97=97=97=97=97=97=97=97 34 |&nbs= p; 3 | 3 | | 12 | &= nbsp; =97=97=97=97=97=97=97=97=97=97=97 3 | &nbs= p; | 3 | 4 | = | 3 =97=97=97=97=97=97=97=97=97=97=97 3 | = ; | | | = ; 3 | =97=97=97=97=97=97=97=97=97=97=97 &= nbsp; | | 4 | = ; | 4 | 3 We w= ere supposed to move back all the spaces in it at the end. Note: = If implemented this prog using recursion, would get higher preference.

Write a prog to accept a given string in any order and flash error if any of the character is different. For example : If abc is the input then abc, bca, cba, cab bac are acceptable, but aac or bcd are unacceptable.

A program that will create a movie seat reservation. The program will display the summary seats and its status. The user will be ask what seat no. to be reserved, then it will go back again to the summary to display the updated seat status. If the seat no. is already reserved then it will prompt an error message. And also if the input seat no is out of range then it will also prompt an error message. The program is continuously running. Termination of the program will depends on how the programmer will apply. Sample output: Movie Seats Reservation Summary of Seats: Seat 1: Available Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 1 Movie Seats Reservation Summary of Seats: Seat 1: Reserve Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 6 The Seat no. is out of range! Movie Seats Reservation Summary of Seats: Seat 1: Reserve Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 1 The Seat no. is already reserved! Movie Seats Reservation Summary of Seats: Seat 1: Reserve Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 0 GoodBye... Thank You!!!
