Assign value (assign)

 

Assign value (assign)

Syntax:

Basic_string & assign (const basic_string & Str); basic_string & assign (const char * STR, size_type num ); basic_string & assign (const basic_string & STR, size_type index, size_type Len); basic_string & assign (size_type num, char ch );

Assign values using the following columns:

• Assign values to strings using STR,
• Use the start num character of STR to assign a value to the string,
• Assign a value to the string using the substring of str. The substring starts with an index and its length is Len.
• Use the num character ch to assign a value to the string.

For example:Code:

 

String str1, str2 = "War and Peace"; str1.assign (str2, 4, 3); cout <str1 <Endl;
