Consider the following program with only the variable declarations shown. For each statement below, specify whether it is true or false and explain why.

int x;

void alpha(int a){

int b;

}

void beta() {

static int k;

}

void gamma(int x) {

}

int main(){

int x, y, z;

{

int y, z;

}

}

1. Function alpha can access the external variable x

2. Function main has access to the static variable k declared inside function beta

3. In the inner block of the main function, the block variable y hides the local main variable y

4. Function beta is the only function that can access global variable x

5. In function main, local variable x is not accessible inside the inner block
