For loop doubts

#1

int a[5]
for(i=0:i<=5:i++){
cout<<a[i]
ignore the colon here why loop is used to print the values or accesing the elements

#2

If you want to print all the elements in an array then you use for loop, but if you want to print a single index in an array.
You can refer to this too


Here it’s printing 3rd index of the array which is 6, you can add particular index to i , to print that index.

#3

no my question is iterator variable i is used for iterating array or printing

#4

It’s used for both, iterating over elements as well as printing them too.
