Question { TCS, 6092 }

What is the output of below code?

{
static in a=5;
printf("%3d",a--);
if(a)
main();
}

Answer

54321

here main() is called again in main function
this leads to recursion....

the function is called until a become 0.
value is retained as static key word is used.

not much clear about usage of "%3d"
