0x08048364 <main+16>:   mov    DWORD PTR [ebp-4],0x1
puts the value 0x1 (1) into "DWORD PTR [ebp-4]" which is our first variable also known as a

0x0804836b <main+23>:   mov    DWORD PTR [ebp-8],0x1
puts the value 0x1 (1) into "DWORD PTR [ebp-b]" which is our second variable also known as b

0x08048372 <main+30>:   mov    eax,DWORD PTR [ebp-8]
moves the value of DWORD PTR [ebp-8](b) into eax the value is also known as 1

0x08048375 <main+33>:   add    eax,DWORD PTR [ebp-4]
adds the value of DWORD PTR [ebp-4](a) into eax, eax now has a total value of 2

0x08048378 <main+36>:   mov    DWORD PTR [ebp-12],eax
moves the value of eax (which is 2) into DWORD PTR [ebp-12] which is our third variable also known as c
c now contains the value 2
