problem in template programing

#include<iostream>

using namespace std;

template <class t>
t min1(t *x)
{
int i=0;
t m;
m=x[0];
while(x[i]!='\0')
{
if(m > x[i])
{
m = x[i];
i++;
}
}
return m;
}

int main()
{
int i;
int a[10];
//float b[10];
for(i=0;i<3;i++)
{
cout<<"Enter the values of a"<<endl;
//for(i=0;i<10;i++)
cin>>a[i];
}
cout<<"enter complete"<<endl;
//for(i=0;i<10;i++)
/*cout<<"Enter the values of b"<<endl;
for(i=0;i<10;i++)
cin>>b[i];*/
cout<<"minimum value is a"<<min1 <int> (a)<<endl;
//cout<<"minimum value is b"<<min1(b)<<endl;
return 0;
}

[335937@oracleclient FIN]$ ./a.out
Enter the values of a
1
Enter the values of a
2
Enter the values of a
3
enter complete



Nothing is displayed after that.

Code:

#include<iostream>

using namespace std;

template <class t>
t min1(t *x)
{
int i=0;
t m;
m=x[0];
for(int i=0;i<3;i++)
{
if(m > x[i])
{
m = x[i];
i++;
}
}
return m;
}

int main()
{
int i;
int a[10];
for(i=0;i<3;i++)
{
cout<<"Enter the values of a"<<endl;
cin>>a[i];
}
cout<<"enter complete"<<endl;
cout<<"minimum value is a"<<min1 <int> (a)<<endl;
return 0;
}


Dont use NULL to check the end of an array. All Arrays doesnot ends with NULL. Only character array has NULL value at the end.

thank you. BUt how to check the end of the integer array..
