Inserting or deleting characters in a string: Library function or modules are provided by the programming languages to perform insert and deletion operations. Inserting: The pseudocode library modules that are used to insert the values is : insert (string1,position,string2) The above function will insert the “string 2” to the “string1” at the “position” specified. “string1” and “string2” is string “Position” is an integer. Deleting: The pseudocode library modules that are used to insert the values is delete (string1,start,end) The above function will delete the strings that are specified from the start to the end. “Start” and “End” is integer that specifies the beginning position and end position. “String” is string. Example: The below statement is used to delete the first three characters from the string “city”. //deletes first three character in city delete (city, 0, 2) Explanation: The above function will delete the strings present in the “city” variable that is specified from the position “0” to the position “2”. The above function will delete the first three character of the “city” string. On execution, the “city” will hold “ton” as its value.

The pseudocode library modules that are used to insert the values is

delete (string1,start,end)

The above function will delete the strings that are specified from the start to the end.

“Start” and “End” is integer that specifies the beginning position and end position.

“String” is string.
