Question

/* C++ Program using strings */
int main() {
char str[]="Test";
int len = strlen(str);
for(int i=0;i<len;i++)

[ Output of the above program is coming as :
TTTT
eeee
ssss
tttt ]
Like I am not able to get what is i [str] and that all.

Answer 1

i[str] == *(i + str)

So basically you are doing the same as normal str[i].

The difference is you are checking the address of i first
and and making a sum with first posittion of str after.

Its same effect
Like
2+4 = 6
4+2 = 6

You are just operating in reverse order.

Answer 2

Okay and can you also explain the working of i[str] ???

Answer 3

Ohhh
Thank You Very Much For Your Help 😊

Answer 4

Anya Ok but how will the *(str + i) work ??

Answer 5

Keshav No 😅

Answer 6

str[¡] == *(str + i)
i[str] == *(i + str)

They all have same effect

Answer 7

Basically

*(address)

So

*(str + i)
str store first address position of array. And i it's the value to iterate.

So *(str + 2) -> str[2]

* means access the value in follow address.
