[detorresrc]

#include <string.h>

int main(){
  char mystring[100];
  strcpy(mystring, "Rommel");
  strrev(mystring);
}

#ERROR
`strrev' undeclared (first use this function)

please help me how to fix this.

I assume strrev() reverses the string? There is no such equivalent to the best of my knowledge. You'll need to implement your own.

#include <algorithm>

template< typename T, size_t N >
void reverse_array( T array[ N ] ) {
   for( size_t i = 0; i < N / 2; ++i )
       std::swap( array[ i ], array[ N-i-1 ] );
}
