What is difference between sizeof and strlen?

Strlen method is used to find the length of an array whereas sizeof() method is used to find the actual size of data. Strlen() counts the numbers of characters in a string while sizeof() returns the size of an operand. Strlen() looks for the null value of variable but sizeof() does not care about the variable value.

Does strlen include null terminator?

strlen counts the elements until it reaches the null character, in which case it will stop counting. It won’t include it with the length. strlen() counts the number of characters up to, but not including, the first char with a value of 0 – the nul terminator.
