declare the array int myarray[]={10, 11, 12, 13}; myarray length is 4because it contains 4 elements that are indexed starting from 0 So the firts element of the array (10 in the example) is in the 0 position cout<<myarray[0]; will output the value stored in the 0 position (first element)of myarray: 10. cout<<myarray[1]; will output the value stored in the 1 position (second element) of myarray: 11.

1.you can enter data into them by using a for loop. eg. int numbers[5]; //array of 5 elements,index 0 to 4 for(int x=0;x<5;x++){ cin>>numbers[x]; } 2. can use them ,for example, to calculate the square of each element and display them. int temp; for(int i=0;i<5;i++); temp = numbers[i]*numbers[i]; numbers[i]=temp; cout<<numbers[i]<<endl; }
