Question

Are the following claims true or false? If false, please explain why and correct it. Declaration int a [1 theta]; declares an array that contains 10 int variables, and their indices ranges from 0 to 10, that is, they are a[theta], a[1], ,a[7], a[8], a[1theta]. Declaration int a [1 theta] ={1,2}; only initializes the first two variables a[0], a[1] to contain 1 and 2, respectively. The other variables in the array contain garbage values. Suppose that declaration int a [1 theta]; is written inside a main function. Then C++ allocates 10 bytes for the entire array a. Suppose that int fun1(int& x) is correctly defined, then the following statement is not allowed in C++ because a[2] is an indexed variable, which should not be passed to a call-by-reference parameter of a function. Function declaration int funl(int x[]); is not correct, as formal parameter x[ ] does not contain an integer between the two brackets. For example, it should be something like int fun1(int x[1 theta]);

Explanation / Answer

a)False
It declares till a[9] only.
b) True
Remaining values may be 0 or garbage depending on where you declare
c)False
It declares 4*10 bytes of memory.as each int occupies 4 bytes
d) True
int &x doesnt compile for cpp compiler
e) False
array should be sent as parameter like int x[ ] only
