How does it takes 7th character("X") from IndiaBIX? 7["IndiaBIX"] shall we define like this?

printf("%c\n", 7["IndiaBIX"]); It is printing the 7th character of the string "IndiaBIX". I-0, n-1, d-2, i-3, a-4, B-5, I-6, X-7.

I think when we write like that then compiler will skip first 6 letters &then print remaining.

@narender no you are wrong. @samini good thnx. :).

Hey program is good, because whenever complier can't define any data type or user define %c means char or you can modify this program or define %f, %d then you will get satisfied answer.

Ya correct guys, if it is printf("%d",7[indiabiA]); means it will print the integer values as A=65

Actually: num[i]<=>(num+i)<=>(i+num)<=>i[num] So 7 is index and indiabix is string. Thus X of indiabix.

It is just trick of mathematics. a[3] = 3[a] --> they are commutative both are expanded by compiler as (a+3) and (3+a) respectively. Even you can assign a variable to 3[a] = "X" which is same as a[3]="X".

Thanks venky, raghu and shamini.

No need to think more. 7["givenstring"] means it take 7th char of that string. And string starts from 0 index. Here "r".

They have used %c so it will take one character and 7 is given and x is at 7 position.

No it will not print all the characters after 6 characters. if we keep 7+"IndiaBIX" then we will get output as you told..@narendra

It will print all characters after x in the string since there is only one character left it prints x

Suppose take an example... int a[3]={10,20,30}; printf("\n%d%d%d",0[a],1[a],2[a]); same way as a[0] a[2].... in the above example 7 is treated as index. So it takes 7th character
