executable

I have a program written in C, which is named computeWeight.c and to compile it i use the following code

chaitu@ubuntu:~$ gcc -Wall -o computeWeight computeWeight.c
//to execute it:
chaitu@ubuntu:~$ ./computeWeight

Do i have any mechansim where i can directly use as mentioned below,

chaitu@ubuntu:~$ computeWeight

Should i be changing any permissions on the executable to get this?
