sizeof(array_of_char) outputs strange number

I'm writing this code to use sizeof() function with a char array of 7 elements, I thought that the output should be 8 because of the 7 elements PLUS the terminator of the array but surprised that the output was 5?? HOW COME?

#include<stdio.h>

int main(void)
{
    char str[]="S\065AB";
    printf("\n%d",sizeof(str));

return 0;
}

Use:

char str[]="S\\065AB";

instead of

char str[]="S\065AB";

\065 is a C escape sequence.

\065 is a single character, represented as an octal escape sequence.
