Question

If a variable is declared both locally and globally, it is treated as if it were two different variables, and the __________ declaration takes precedence.

Answer 1

Hi There,

Please find my explanation below. Please comment below in case of any concerns or if you have any queries.

When a variable is declared both locally and globally, the LOCAL declaration takes precedence.

I will explain this with a C programming example:

#include <stdio.h>

//global variable declaration
int variable = 20;

void precedence_test(){
//local variable declaration
int variable=10;
printf ("Local value of variable = %d\n", variable);

}
int main () {

printf ("Global value of variable = %d\n", variable);
precedence_test();
return 0;
}

Output:

As we can see here, the Global value of the variable is 20. When the same variable is declared with the value 10 locally in a function, the variable value in local declaration takes the precedence and prints 10 and not 20.
