C Exercises: Create enumerated data type for 7 days and display their values in integer constants
C Basic Declarations and Expressions: Exercise-60 with Solution
Write a C program to create enumerated data type for 7 days and display their values in integer constants.
Pictorial Presentation:
Sample Solution:
C Code:
#include <stdio.h>
int main()
{
enum week{Sun, Mon, Tue, Wed, Thu, Fri, Sat};
printf("Sun = %d", Sun);
printf("\nMon = %d", Mon);
printf("\nTue = %d", Tue);
printf("\nWed = %d", Wed);
printf("\nThu = %d", Thu);
printf("\nFri = %d", Fri);
printf("\nSat = %d", Sat);
return 0;
}
Sample Output:
Sun = 0 Mon = 1 Tue = 2 Wed = 3 Thu = 4 Fri = 5 Sat = 6

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
