String Handling

The combination of different characters is called as string data. The “char” data type is used to create character or string variable both.

The control string “%S” is used to input and output string data

     §   String array: -     When we want to store more than one string in one string variable then we need to create string array.

     §   String handling functions: -     Since string data cannot be operated normally by using arithmetic, relational assignment operators etc. so ‘C’ supports a no. of pre-defined function which are used to perform the operation on string data. These functions are called as string handling functions.

These functions are as follows:-

     a.     strcpy()

     b.     strncpy()

     c.      strcat()

     d.     strncat()

     e.     strrev()

     f.       strlwr()

     g.     strupr()

     h.     strlen()

     i.        strcmp()

     j.       stricmp(), etc.
