Char array index output in C

Question

When I tend to output the char array indices
i.e char_array[0] and char_array[1]
with the help of printf() function.
You can see that code below.

I use two type of format specifier (%c and %d) in printf() function for each char_array indices separately
.
Output comes from %c specifier gives a expected output
But I won't understand the output comes from %d format specifier

And I also confuse how does char_array index support %d format specifier

Answer 1

Thank you Abhay ,Adnan Chowdhury and codemonkey.
I ask these types of questions frequently because i am new to C programming
Anyway thank you Friends :)

Answer 2

Yup that works as expected ,it actually print a character output for %c as you mentioned ,and ASCII value for that character using %d

Answer 3

Because the ASCII value of e=101 and h=104. When you print in decimal of e and h it prints the ASCII value of e and h.
