spell bob august challenge..whats wrong in my code....the error being shown is run time eror

#include
using namespace std;
int check(char exp1[],char expp2[]);
int main()
{
int t;
cin>>t;

int k=0;
	int a[k]={0};
	
while(t-->0)
{
	
	char exp1[3],expp2[3];
	cin>>exp1;
	cin>>expp2;
	int countb=0,counto=0,i,j;
	int f=check(exp1,expp2);
	for(i=0;i<3;i++)
	{
		if(exp1[i]=='b')
		countb++;
		else if(exp1[i]=='o')
		counto++;
		else
		continue;
	}

	for(i=0;i<3;i++)
	{
		if(expp2[i]=='b')
		countb++;
		else if(expp2[i]=='o')
		counto++;
		else
		continue;
	}
	
	if(f==1&&countb>=2&&counto>=1)
	a[k++]=1;
	else
	a[k++]=0;
//	cout<<"t="<<t<<endl;
	
}
for(int i=0;i<k;i++)
{
	if(a[i]==1)
	{
