return 0;

}

#include

int main () {

struct employee {

int id;

char name[20];

} emp; // The structure variable `emp` is declared here.

int n[5] = {0, 7, 0, 3, 8, 2};

Constant variables ______

-can be assigned values in executable statements

-can be used to specify array sizes, but this makes programs harder to

-understand

-can be used to specify array sizes, thereby making programs more scalable --do not have to be initialized
