Discussion Forum : Const - Find Output of Program (Q.No. 10)
10.
What will be the output of the program?
#include<stdio.h>

int main()
{
    const c = -11;
    const int d = 34;
    printf("%d, %d\n", c, d);
    return 0;
}
Error
-11, 34
11, 34
None of these
Answer: Option
Explanation:

Step 1: const c = -11; The constant variable 'c' is declared and initialized to value "-11".

Step 2: const int d = 34; The constant variable 'd' is declared as an integer and initialized to value '34'.

Step 3: printf("%d, %d\n", c, d); The value of the variable 'c' and 'd' are printed.

Hence the output of the program is -11, 34

@arup.

If we write const d=12.34
Then d By default treated as int data type and it store 12

Example:

#include<stdio.h>
int main()
{
const c = 12.34;
const int d = 34;
printf("%d, %d\n", c, d);
return 0;
}

Output:
12, 34

#include<stdio.h>

int main()
{
const c = "araf";
const int d = 34;
printf("%s, %d\n", c, d);
return 0;
}

output : araf, 34
So it c is of any type.

If we write that const d=-12; d will be treated as int data type. By default const is int data type.

I am getting an error: 'c' does not name a type. Can anyone tell me why I am getting this error?

In g++ compiler, it showing error as 'c' was not declared in this scope.

Can anyone help me?

In statement const c = -11
c will be declared as what data type ?
And how?

In C++ Shell compiler, it is treated as an error.

What should I do?

The const values become int by default, not any one can be default.
