Which one is false regarding global variables?Global variables can only be read inside the function declaring the variable as global inside the function.Global variables remain in memory till the end of the programGlobal variables are those which are declared in global scope.None of the above

Provide the correct answer(s) in the blank(s) Global variables are declared outside of any function. A global variable is visible to any every function and can be used by any piece of code. Unlike local variable, global variables retain their values between function calls and throughout the program execution. Let us consider an example: #include < stdio.h > int a = 20; // Global declaration void test(); void main() { printf("In main() function a = %d\n", a); // Prints 20 test(); a = a + 15; // Uses global variable printf("In main() function a = %d\n", a); // Prints 55 } void test() { a = a + 20; // Uses global variable printf("In test() function a = %d\n", a); // Prints 40 } In the above code the global variable a is declared outside of all the functions. So, the variable a can be accessed in every function. Operating System calls the main() function at the time of execution. the variable a has no local declaration, so it access the global variable a. In test() function also there is no local declaration of variable a, the variable a gets access from the global. The global variables are destroyed only after completion of execution of entire program. What is the output for the following code #include <stdio.h> int a = 10; void test(); void main() { printf("In main() function a = %d\n", a); test(); a = a + 10; printf("In main() function a = %d\n", a); } void test() { a = a + 20; printf("In test() function a = %d\n", a); }

Which of the following is true about Python's global keyword?AIt can only be used inside functionsBIt makes a variable local to the functionCIt declares a variable as globalDIt prevents the use of global variables

Marks statements as True or False.True False A global static variable is visible in entire program, in multiple files A local static variable is visible only in the file , but in all functions of that file A local variable is visible only in that function A global variable is visible in entire program, in multiple files

define Local and Global variables and the difference between them

Where are variables with global scope accessible?
