End1 not defined

End1 is not defined-General Linux technology-Linux programming and kernel information. The following is a detailed description. In linux, use vim to write the program as follows:

# Include

Int main ()
{
Using namespace std;
Int carrots;
Cattots = 25;
Cout <"I have ";
Cout <carrots;
Cout <"carrots ."
Cout <end1;
Carrots = carrots? 1;
Cout <"Crunch, crunch. Now I have" <carrots <"carrots." <end1;
Return 0;
}

When compiling with g ++, the system prompts that end1 is not defined. what is the problem?
If you delete end1, it can be compiled normally. Will the display result be faulty?
Do I have to add spaces on both sides?
