Which is the right way to declare constant in C?Question 33Select one:A.int constant var =10;B.int const var = 10;C.const int var = 10;D.B & C Both

The correct way to declare a constant in C is option C: const int var = 10;

Here's the step by step explanation:

1. In C, the keyword 'const' is used to declare a constant.

2. The type of the constant is specified after the 'const' keyword. In this case, it's 'int' which stands for integer.

3. Then, you give a name to the constant. Here, it's 'var'.

4. Finally, you assign a value to the constant using the '=' operator. Here, the value is 10.

So, the correct syntax is: const int var = 10;

Option D is incorrect because while option B has the correct keywords, the order is incorrect. The 'const' keyword should come before the type of the constant.
