Segment Violation

I cant find the last segment violation, I think its in line 26 but I dont know what it should be.

#include "stdio.h"
#include "string.h"

// function prototypes
void strrvr( char outstr[] , char instr[] );

// driver
int main()
{
char outstr[100];
char instr[100]="emordnilap";
strrvr(outstr, instr);
printf( "%s\n", outstr );
return( 0 );
}

// strrvr function
void strrvr(char strout[], char strin[])
{
int i;
int n = strlen( strin );
strout[i] = strout[n]; // copy the null string terminator
for (i = 0 ; i < n ; i-- )
strout[n-i-1] = strin[n];
}

To all faggots who think size_t is a separate type and not an integer:
size_t is just a typedef, it even says so in the C99 standard
