Question

Not related to gate but genral programming..

if some one ask me array indexing start from 0,yes i know array indexing start from 0 . but can i also say sometime if i want array indexing is also start from 1 what happen if indexing satrt from 1 insted of 0.

how can i proff that indexing    start with 1.

i know Array  indexing tell me how many  steps ahed are from the first position of array,

Can you rephrase your question? I didn't get what's your exact doubt is.

 

Array indexing starts from 0 in C language. However I can write a C program, which takes array index from 1 (Though internally i may skip 0 index add one more index at the end).

@Shaik Masthan sir i solve alot of  gate question in which  they ask  address and specialy mentioned that  if array index start with 1.this confuse me in a personal interview.

i told to interviewr that i can also start array from 1 insted of zero. am i wrong?

basically indexing from zero meance how many element you skipfrom starting but if i start indexing with 1 can i say that i skip one element.

RIP my english.

If a[]={a,b,c,d,e} , what is a[2] ?

- if index starts from 0, then answer is 'c'

If index starts from 1, then answer is 'b'

If index starts from -2, then answer is 'e'

Here theoretically,  they define starting index.

But if you write C program,  by default it will give 'c' as answer due to in C language,  index starts from zero.

 

However, if I write code as

N = number of elements as input.

A[n+1] - define an array with n+1 elements.

for(i=1, i<=n; i++)

   Collect and store the input in a[i]

If you want to read the input from array, use a[index+1] ------ This way I can implement array index starting with 1
