Operating an Array
Lesson 2 of 26 in Coddy's Arrays in C++ course.
Before operating an array we should keep in mind two terms: Element and index.
- An Element is data that has been stored at the place.
- An Index is a position at which the data has been stored.
For example,
{3,8,1,0,5,-2,32} in this array the number 3 is at the 0th position, the number 8 is at the 1st position, and so on.
If we receive multiple elements from the input, then we can use a for loop for that and store the values as
int arr[5];
for(int i=0;i<5;i++){
cin>>arr[i];
}Similarly, we can output the elements of the array using for loop.
for(int i=0;i<5;i++){
cout<<arr[i]<<" ";
}
cout<<endl;
Challenge
Declare an array of integers of size 5 names as arr.
Take input from the user, and print the square of each element separated by space.
Try it yourself
#include<iostream>
using namespace std;
int main(){
//Write your code here
return 0;
}
