assigning a string to another string

Question

Why this code is not running? Why str1 is not assigned to str2 ?? I know i have an option of using strcpy but i wish to know the reason why this is not working??

Answer 1

str2 and str1 refers to the address of their first elments so assignment of arrays is not done in this way use either str[] to assign char by char or use inbuilt strcpy
