<\/span><\/h2>\n\nThe default value of an enum in C is the first enumerator<\/b> in the list of constants. In other words, if no explicit value is assigned to the enum variable during declaration, it will automatically be set to the first defined constant.<\/p>\n
Consider the following example:
\n“`c
\n#include <\/p>\nenum Days {
\n MONDAY,
\n TUESDAY,
\n WEDNESDAY,
\n THURSDAY,
\n FRIDAY,
\n SATURDAY,
\n SUNDAY
\n};<\/p>\n
int main() {
\n enum Days today;
\n printf(“Today is %dn”, today); \/\/ Output: Today is 0
\n return 0;
\n}
\n“`
\nIn this code snippet, we define an enumeration called “Days” with seven constants representing each day of the week. The enum variable “today” is declared without an explicit initialization. Consequently, its default value will be the first enumerator, in this case, “MONDAY,” which is associated with the value 0. Therefore, the output of the code will be “Today is 0.”<\/p>\n
It is essential to remember that the default value of an enum can be overridden by assigning an explicit value to the variable during declaration. Furthermore, subsequent enumerators in the list will have automatic values incremented by 1 from the preceding enumerator.<\/p>\n
