Question

Explain how for loops can be used to work effectively with elements in an array?

Answer 1

Explanation:

There are three types of loops in programming languages which are as following:-

1. for.
2. while.
3. do while.

The syntax for all the three loops is different.You will see mostly for loop used with the arrays because they are easy to implement.

the syntax of for loop is :-

for(int i=initial value;condition;i++)

{

body

}

In for loops you only have to write the conditions in only line else is the body of the loop.

for example:-

for array of size 50 printing the each element

for(int i=0;i<50;i++)

{

   cout<<arr[i]<<" ";

}

You have to initialize i with 0 and the condition should be i<size of the array and then increase the counter.
