How can we use int x=40; as a function. It is giving errors.

Can we use {} in between program when it is not a function or loop ?
I think not.

@Nidhi yes you can.
{
it is consider as a block
}
It don't affect the program, and do not produce any error!!
Moreover the variable within a block gets higher priority.

It will produce an error in Turbo c because all variables should be declared first but here int a=20 is declared after open bracket ( "{").
Please help me to get it.

@Gangadhararo.
The inner loop has x=20. So it prints 20 First (the first pritf stmt is in the inner loop).
The outer loop has x=40. So it prints 40 next the second printf stmt is in the outer loop).
