rrect answerWhich of the following is a valid way to initialize a constant in C?Optionsconst int x = 5;constant x = 5;int const x = 5;int x = const 5;

To determine the correct way to initialize a constant in C, let's evaluate each of the given options:

1. const int x = 5;
   This option correctly declares x as a constant integer with a value of 5. The const keyword is properly placed before the data type.

2. constant x = 5;
   This is incorrect because constant is not a valid keyword in C for declaring constants. The correct keyword is const.

3. int const x = 5;
   This option is also valid in C. The syntax is equivalent to const int x = 5; as both declare x as a constant integer.

4. int x = const 5;
   This is incorrect because const cannot be used in this manner. The const keyword should precede the type and cannot be used in assignment.

Final Answer

The valid ways to initialize a constant in C are:

• const int x = 5;
• int const x = 5;

Thus, the correct options are the first and third ones.
