Explanation:

Duplicating the content of the source string into the target string is the process of copying a string into another string. This procedure is usually carried out by iterating through each character in the source string and inserting it into the destination string. In languages such as C, this is sometimes done by appending a NULL character to indicate the end of the string.

Logic Steps:

  1. Initialize Variables:
    • Create two strings: one as the source and the other as the target.
  2. Iterate Through the Source String:
    • Loop through each character in the source string.
  3. Copy Characters:
    • Assign each character from the source string to the corresponding position in the target string.
  4. Null-Terminate the String:
    • If necessary (e.g., in C), add a null terminator NULL to the target string.
  5. Output the Result:
    • Display or use the copied string.
