Answer 1

0[arr] is same as arr[0] which value here is 's' ;

Initially arr points to start or 0th element of array. And arr+3 means arr [say location is 1000] pointer added 3 positions farward, now points to arr pointer points to arr[3] [location is 1003] which is 'o'. (note array points from 0 index).
Now 2[arr] means arr[2], and the value is 'e'. [Since now start position is arr+3 is arr[0] that is 'o'. So]
And in printf %d coverts charecter value to ascci or numaric value of 's' which is 115.
So Output is 115 e.
Hope it clears you...

Answer 2

Santosh Chavan 0[arr] and arr[0] both representing the zeroth index in this index value is S capital S and ASCII value of capital S is 83 so it will be 83 and the ASCII value of small s is 115 . Hope you understood.

Answer 3

It's the same as;
char arr[] = "Sololearn";
printf("%d %c", arr[0], arr[5]);

Outputs
83 e
83 is the int value of 'S'

Answer 4

Here's an ascii chart. Look at the values in the Dec (base 10) ("%d") column, under the section printable characters, for the characters.
Capital letters starting at 'A' with the value of 65, increasing by 1 in alphabetical order, range from 65-90. Lower case letters are +32 of their upper case counterparts, and range from 'a' 97 to 'z' 122.

Answer 5

83 for 'S' 115 for 's'

Answer 6

Santosh Chavan if it is small s in sololearn,
Output is 115.
If capital S as SoloLearn then output is 83.
The ascii values of respected characters.
