Program Explanation

Instruction(s) inside the for block{} are executed repeatedly till the second expression (i<=n) is true.

Here i is initialized to 0 and incremented by 1 for each iteration, instructions inside the for block are executed unless i becomes greater than n.

so value of i will be printed like 0 1 2 3 .... n using printf statement.
