What will be the output of the following C code?
    #include <stdio.h>
    void main()
    {
        int const k = 5;
        k++;
        printf("k is %d", k);
    }
  • a)
    k is 6
  • b)
    Error due to const succeeding int
  • c)
    Error, because a constant variable can be changed only twice
  • d)
    Error, because a constant variable cannot be changed
Correct answer is option 'D'. Can you explain this answer?

What will be the output of the following C code? #include <stdio.h...
Constant variable has to be declared and defined at the same time. Trying to change it results in an error.
Output:
$ cc pgm12.c
pgm12.c: In function ‘main’:
pgm12.c:5: error: increment of read-only variable ‘k’

What will be the output of the following C code? #include <stdio.h...
Understanding the C Code
The provided C code snippet contains a few key elements that lead to its output. Let's break it down:
Code Analysis
- The code begins by including the standard input-output library using `#include `.
- The `main` function is defined as `void main()`, which is technically incorrect in standard C but is accepted by some compilers.
- Inside the function, a constant integer `k` is declared and initialized with the value `5` using `int const k = 5;`.
Key Point: Constant Variable
- A variable declared with `const` means that it is read-only and cannot be modified after its initialization.
- The statement `k++;` attempts to increment the value of `k`, which violates the rules of constant variables.
Expected Output and Errors
- Since `k` is a constant, the line `k++;` will generate a compile-time error.
- The compiler will notify that you cannot change the value of a constant variable.
Conclusion
- Therefore, the correct answer is option 'D': "Error, because a constant variable cannot be changed."
- The program will not compile successfully due to the attempt to modify a constant variable.
Understanding these principles will help you grasp the importance of constant variables in C programming.
