stack operations of push, pop, peek, is_empty, and size. You may also use cin.peek( )
and use "cin>>i" to read an integer.
int evaluate_postfix_from_cin( )
// Precondition (Which is not checked): The next input line of cin is a
// properly formed postfix expression consisting of integers,
// the binary operations + and -, and spaces.
// Postcondition: The function has read the next input line (including
// the newline) and returned the value of the postfix expression.
{
int i;
stack<int> s;
may use the stack template class
bool balanced(const char p[ ], size_t n)
// Precondition: p[0]...p[n-1] contains n characters, each of which
// is '(', ')', '{' or '}'.
// Postcondition: The function returns true if the characters form a
// sequence of correctly balanced parentheses with each '(' matching
// a ')' and each '{' matching a '}'. Note that a sequence such as
// ( { ) } is NOT balanced because when we draw lines to match the
// parentheses to their partners, the lines cross each other. On the
// other hand, ( { } ) and { ( ) } are both balanced.
Write a Programmer that will develop a software called VACCINE_OPTION, that will determine the correct vaccine for every candidate. The available vaccines are Moderna, mRNA, Johnson & Johnson’s Janssen and Pfizer-BioNTech
The software should determine the type of vaccine a candidate should receive based on their temperature. Use the switch statement to determine the right vaccine for candidate by using their temperature readings
1. 30-33 for Mordena
2. 34-36 mRNA
3. 37-38 Johnson and Johnson’s Janssen
4. 39-40 Pfizer-BioNTech
The program must be able to read temperatures up to four(4) decimal places after the comma and use an appropriate library to convert it to two(2) decimals after the comma,
people that are vaccinated:
Jay Snow 34,37 mRNA
Chris Van 37,66 Johnson and johnson’s Janssen
Charles Smith 32,55 Mordena
Norwell Sky 39,78 pFizer-BioNTech
-Use an appropriate operator to convert an expression to a specified type
-manage the alignments in the summary of your candidates
Write a program that declares a struct to store the data of a baseball player (player’s name, number of home runs, and number of hits). Declare an array of 10 components to store the data of 10 baseball players. Your program must contain a function to input data and a function to output data. Add functions to search the array to find the index of a specific player, and update the data of a player. (You may assume that input data is stored in a file.) Before the program terminates, give the user the option to save data in a file. Your program should be menu driven, giving the user various choice
Insert, into the first stack, all the data above (which is the data of student’s names,
surnames and the marks they obtain in a particular assessment)
Display the content of the stack on the screen (console)
Then, remove all the students whose surname starts with the alphabets ‘R’, ‘J’ and
‘M’, from the first stack and insert them into the second Stack.
