When a string ends '\0' (null) gets added at its end but does it also gets added at the end of an array if not then what ?

Question

Suppose i declare a string in c++ like this
char s[10]="abcdefghi";
0th position is occupied by 'a' while 8th is occupied by 'i'.
9th position is occupied by '\0'.
Is this also the case with an integer array??

Answer 1

No. If you declare array of Int in int main() function then it has some trash values. When you declare array before Int main() then it has 0 values not '|0'.
