COBOL Interview Questions and Answers

 

What is the difference between a binary search and a sequential search what are the pertinent COBOL?

In a binary search, the table element key values must be in ascending or descending
sequence. The table is ‘halved’ to search for equal to, greater than or less
than conditions until the element is found. In a sequential search, the table is
searched from top to bottom, so (ironically) the elements do not have to be in a
specific sequence. The binary search is much faster for larger tables, while sequential
works well with smaller ones. SEARCH ALL is used for binary searches; SEARCH for
sequential.
