Inserts characters into the string:

1) inserts character ch before the character pointed by pos

2) inserts count copies of character ch before the element pointed to by pos

3) inserts count copies of character ch at the position index

4) inserts null-terminated character string pointed to by s at the position index. The length of the string is determined by the first null character.

5) inserts the first count characters from the character string pointed to by s at the position index. s can contain null characters.

6) inserts string str at the position index

7) inserts a string, obtained by str.substr(index_str, count) at the position index

8) inserts characters from the range [first, last)

9) inserts elements from initializer list ilist.
