Question

char st[] = {‘G’,’A’,’T’,’E’,’\0’};

then string ka length 4 hoga ya 5 with null character?

Comments

you are asking what will be output if we pass it to sizeof() operator?

coz i believe sizeof() does count \0 null character. so it will return $5$

Answer 1

If you use length() method, then it would return 4. But if you use sizeof() method, then it would return 4+1(for null character)=5.

 

Answer 2

The strlen() function calculates the length of the string by counting the number of all characters until it reaches the null terminator ('\0'). So the length of this string “GATE” is 4.
