A comparison between C language sizeof and strlen

Today I saw an algorithm for the topic, said to be merged into two ordered arrays, in an orderly manner.

Look at the thought is very simple, take for granted began to knock on the program, but found a lot of small problems, these are the basis ah, prominent is the sizeof () problem.

sizeof () Gets the length of the occupied byte of a type (I actually used to get the length of the array)

Strlen gets the length of the string (I'm still used to get the length of the array)

Two times after the fall, I do not do these boring attempts, carefully look for problems.

Find the definition and start using the

sizeof (Array)/sizeof (array[0]), so that the length of the array is obtained.

There are a number of sizeof (), such as byte alignment.
