Scope resolution operator program

Unfortunately, C programming doesn't support scope resolution operator. So by making using C Plus Plus with an extention .cpp to learn scope resolution operator for future use.

#include <stdio.h> //header file section
int value();        // function declaration
int a = 7;          //variable a is declared globally
int main()
{
value();           //calling a function
return 0;
}
int value()
{
int a = 5;
printf("The value of a = %d ",a);
printf("\nThe value of a = %d ",::a);
return 0;
}
