Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffeef3ffff8) - c++

Question

#include <iostream>
#include <string.h>
using namespace std;
int palindrome(char str1[], int n){
int result = 1;
for(int i = 0; i<=(n/2)-1 ;i++){
if(str1[i]!=str1[n-1-i]){
result = 0;
break;
}
}
return result;
}
void copyArrayChar(char *src, char *dest,int startSrc, int size){
for(int i=0; i<=size-1; i++){
src[startSrc + i] = dest[i];
}
}
int patternj(char str1[], int n){
int result = 0;
int check;
check = palindrome(str1, n);
if(n==1||n==0){
result = 1;
} else if(check == 1){
char strL[n/2], strR[n/2];
copyArrayChar(str1, strL, 0, n/2);
copyArrayChar(str1, strR, (n/2)+1, n/2);
result+= patternj(strL,n/2) + patternj(strR, n/2);
}
return result;
}
int main(int argc, const char * argv[]) {
string str[100000];
int strLength[100000], result[100000];
char str1[100000][100000];
int ni;
cin >> ni;
for(int i=0;i<=ni-1;i++){
getline(cin,str[i]);
strLength[i] = (int) str[i].length();
str[i].copy(str1[i],strLength[i],0);
result[i]= patternj(str1[i], strLength[i]);
}
return 0;
}
Hi, so I've written this code to check for patternj strings but for some reason it gives me an error with this name "Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffeef3ffff8)". I don't quite understand why this is happening.
