From the definition of const qualifier, that the variable value cannot be changed in the current file, but can be changed in another file, I tried to write the program but resulted in segmentation fault.
file1.c
file2.cCode:#include<stdio.h> const int x = 5; void main(){ printf("%d",x); show(); }
Please help me..Code:void show() { extern int x; x++; printf("%d",x); }
Honesty is the best policy.

Please tell me what is wrong in this....
The variable is declared as const. It's not allowed to modify it under any circumstance.
Perhaps you're trying to come up with an example where a value is allowed to be modified in one function but is read-only in another?
For that you could have a non-const global variable, and one function that just happily assigns to it, and another that takes a pointer to const which is passed the address of variable.
