How to use arrays in c

Answer 1

int a[5] = {1,2,3,4,5};
printf("%d\n",a[1]);

//prints 2 as array index starts from 0

Answer 2

using the for function

Answer 3

for (int i = 0; i < ARRAY_SIZE; ++i)
do_something_with(a[i]);

This will do something with all array members.

Answer 4

https://code.sololearn.com/cV2cJ89sVK5d/?ref=app here i made an array, gave it some values in the for loop, and then used for loop to print out those values

also this is my first code in C and not C++, feels weird
