Predict the output or error(s) for the following

main()
{
static int var = 5;
printf("%d ",var--);
if(var)
main();
}
Answer:



5 4 3 2 1
Explanation:
When static storage class is given, it is initialized once. The change in the value of a
static variable is retained even between the function calls. Main is also treated like
any other ordinary function, which can be called recursively.
