Adding the elements of a list sequentially

I am looking for an efficient way to add the elements of a list 
sequentially onto another list

For example, generate list c, given lists a and b:

a = {1,2,3,4,5,6,7,8,9,10}
b = {1,2}

c = {2,4,4,5,6,7,8,9,10,11}


another example:

a = {1,1,1,1,1}
b = {1,2,3}

c = {2,3,4,2,3}

It seems like there must be a built in function to do this, but 
have been unable to find it.


Thanks a 10^6
