Question

I need help please for class.

Answer 1

This week, you need to create a console-based application whose Main() method accepts ten integer values from the user and stores them in an array. Next, create a method that determines and displays the smallest and largest of the ten values. Then, pass the array to the method.

Answer 2

Next, create a GUI application whose button's Click() method accepts ten integer values from a TextBox and stores them in an array that is declared above the Click() method. After ten entries have been made, call a method that determines and displays the smallest and largest of the ten values.

Answer 3

What programming language are you using?
for C++
int main(){

int number[10]; //an array of 10 int
for(int x=0; x<10;x++){
cin >> number[x];
}
// do some comparison something like
// if number[0] > number[1] then store it in a temp variable.
}
This should get you started.
