Answer:

C is a block-structured language. Blocks are delimited by { and}. Every block can have its own local variables. Blocks can be defined wherever a C statement could be used. No semi-colon is required after the closing brace of a block.

Code:


#include<stdio.h>
#define semicolon ;
void main() 
{
 
  int a = 5;
  printf("\n%d", a);
  
  {
  int  a = 2;
  printf("\n%d", a);
  }
 
	
}
