I was the following...

Write a program that displays a menu with the following choices to the user.

A - Find the largest # with a known quantity of numbers

B - Find the smallest # with an unknown quantity of numbers

C - Quit

Please enter your choice ___

This menu needs to be repeatedly displayed until the user chooses to quit.

If A is chosen, you should ask the user how many numbers he wants to enter. If he enters 5, you should read 5 numbers from him. You should then display the largest number he entered. Use a for loop to read these and display the largest.

If B is chosen, you should keep reading numbers no matter what until the user enters -99. Then you should display the smallest number he entered not counting the -99.

can you help me get started?

revision: change to public

to find the largest number entered by a user, you do not need to store all the numbers in memory. this would do:

a. initially make the first number entered by the user the largest number.

int largest_so_far ;

std::cin >> largest_so_far ;

b. read the remaining numbers in a loop and check against the largest so far read.

begin loop:

int number ;

std::cin >> number ;

if( largest_so_far < number ) largest_so_far = number ;

end loop

the only difference between options A and B is the kind of loop you would write.

A:

int N ; // how many numbers

std::cin >> N ;

int largest_so_far ;

std::cin >> largest_so_far ; // read first number

for( int i=1 ; i<N ; ++i ) // read remaining N-1 numbers

{

// ...

}

B:

int largest_so_far ;

std::cin >> largest_so_far ; // read first number

int number ;

while( ( std::cin >> number ) && ( number != -99 ) )

{

// ...

}

my primary areas of interest are generic and template metaprogramming, STL, algorithms, design patterns and c++11. i would not answer questions about gui and web programming.
