Select all the true statements:

  • The “C” language compiler is case-sensitive
  • The reserved keywords cannot be used as variable names
  • You can write multiline comments in the “C” language
  • The decimal value of 012 (octal) is 10
  • Nesting comments is a recommended pratice
  • The decimal value of 0x11 (hexadecimal) is 16
Explanation & Hints:

Here are the true statements from the options provided:

  1. The “C” language compiler is case-sensitive – This is true. In C, identifiers (including variable names, function names, etc.) are case-sensitive, meaning that Variable, variable, and VARIABLE are considered different identifiers.
  2. The reserved keywords cannot be used as variable names – This is true. In C, reserved keywords, such as int, return, and for, are part of the language syntax and cannot be used as variable names because they have predefined meanings in the language.
  3. You can write multiline comments in the “C” language – This is true. In C, multiline comments start with /* and end with */, allowing comments to span multiple lines.
  4. The decimal value of 012 (octal) is 10 – This is true. In C, numbers starting with a zero are considered octal (base 8). Therefore, 012 in octal is equal to 10 in decimal.
  5. The decimal value of 0x11 (hexadecimal) is 16 – This is false. 0x11 in hexadecimal actually equals 17 in decimal. The correct computation is 1×161+1×160=16+1=17.
  6. Nesting comments is a recommended practice – This is false. In C, nesting comments is not supported by all compilers and can lead to errors or undefined behavior if attempted. Therefore, it is not a recommended practice.

Thus, the true statements are the first four options.
