What will strcmp() function do?

  • A.compares the first n characters of the object
  • B.compares the string
  • C.undefined function
  • D.copies the string

Answer: B

Correct answer: compares the string

strcmp() compares two null-terminated strings and returns a negative value, zero, or a positive value according to whether the first sorts before, equal to, or after the second. The comparison is by character code, so it is not the same as alphabetical order for mixed case. The first n characters version is strncmp().
