Discussion Forum : Const - Find Output of Program (Q.No. 9)
What will be the output of the program?

int main()
    const int i=0;
    printf("%d\n", i++);
    return 0;
No output
Error: ++needs a value
Answer: Option

This program will show an error "Cannot modify a const object".

Step 1: const int i=0; The constant variable 'i' is declared as an integer and initialized with value of '0'(zero).

Step 2: printf("%d\n", i++); Here the variable 'i' is increemented by 1(one). This will create an error "Cannot modify a const object".

Because, we cannot modify a const variable.
