库函数，用于反转字符串

Question

Is there alternative for strrev() in C? I am interested in a function that does the same but it must be included in the standard library.

I am aware that operation can be easily implemented by user defined function but I am looking for a library alternative.Precisely there are few functions take for example rindex (identical to strrchr() ) which is more common in perl but still works in gcc-4.3.4,I am inquisitive to know if there is anything like that for strrev() since the common reversing function in perl ie reverse<> is not working in C.

Compiler specification: [C (gcc-4.3.4)]

Thanks,

PS:I am aware of C++'s STL reverse but my question is strictly about C.

Answer 1

As far as I know, there is no such a function in C standard libraries. If you don't mind using C++, there is reverse template function in algorithms .

Answer 2

1 .The strrev you are aware about is:

Using Loops

2 . Refer this link: http://fresh2refresh.com/c-programming/c-strings/c-strrev-function/

3 .In Turbo C the strrev() library function is available.

#include<stdio.h>
#include<conio.h>
int main()
{
   clrscr();
   printf("%s",strrev("string"));
   getch();
   return 1;
}
