Question

Introduction to Arrays. Please make sure program compiles :)

int numlist[8]; // declare int array that can store 8 values If we wish to fill the array numlist with the integers typed from the keyboard, you can use a for loop. Here is a for loop that will allow you to enter 8 values from the keyboard and will store them in the array numlist. Notice that we have used the variable i as an index for array numlist for (i = 0: 8: i++) cout <<"Enter the next value: ". cin >> numlist[ij It might be easier for our user to keep up with different values that need to be entered if we display something more helpful than "Enter the next value: ". Since users typically number items in a list starting from 1, we will say "Enter value #1: " when asking for numlist [0] , "Enter value #2: " when asking for numlist [1], and so forth. Here is the improved version of the loop: for (i 0: i < 8; i++) cout << "Enter value << i+1 << ": ". cin >> numlist[i;

Answer 1

#include <iostream>

using namespace std;

int main()
{
int numlist[8];
for(int i=0; i<8; i++){
cout << "Enter value #:"<<i+1<<": ";
cin >> numlist[i];
}
for(int i=7; i>=0; i--){
cout<<"Value #"<<i+1<<": "<<numlist[i]<<endl;
}
return 0;
}

Output:

sh-4.3$ g++ -std-c++11-o main *.cpp sh-4.3$ main Enter value #:1: 12 Enter value #: 2: Enter value #: 3: 23 Enter value #:4: 1000 Enter value #15: 123 Enter value #16: 10 Enter value #:7: 8 Enter value #:8: 12 Value #8: 12 Value #7: 8 Value #6 : 10 Value #5: 123 Value #4 : 1000 Value #3: 23 Value #2: 8 Value #1: 12 8
