Strings In C: C Tutorial In Hindi #34

[@pythonkrishna290]

str[5] can only store 5 characters. The strinng (or character array) "hello" has 5 characters so there's no space for the null character(\0). For those who are wondering that by using double quotes ("") the compiler will automatically add a null character(\0) should remember that altough it's true but the compiler will need an extra space in that array to store the null character(\0) which is limited in the character array str. Hope I am right...

[@adityadoijad8091]

The array str is declared with a size of 5 (char str[5];), which means it can store only 4 characters plus the null terminator ('\0'). However, the string "hello" has 5 characters.

str[5] is an array that can store upto 5 characters only. h e l l o is 5 characters, since the 6th character is a null character the array size has t be 6. Hence, str[6] should be used for storing h e l l o.

[@adnankaisar12]

Sir as you said and we all know element of an array started from 0 so char str[5] is correct according to me cause it has 6 spaces so we can include '\0' too in that if i write "harry". I'm confused sir, coreect me if im wrong.

[@tishagupta3136]

str = "hello" consists of 5 characters and when it's checked by the C compiler gcc then it adds a null character in the end and so the size is 6 but it is initialized with char str[5]; so the second line will throw error as there's no problem in initializing the array but the index is overlapping the declared size of the character array

9:38 Bcoz sir array size is 5 and bcoz we have put double quotation therefore there's no space for it. Hence the string will be printed with garbage values ..So the space should be increased .

in double quotes( " " ) compiler will add a null character to variable hence it will need an extra space is required. Due to this reason line will create an problem. So the size of the string should be at least { length + 1}

Good bro

[@daughter_of_chitkute0611]

the compiler adds the null character by itself as we have declared it as a string hence the size would imply that 4 characters for the string and the last character will be reserved for the '\0'. Therefore, we should always give one extra size while declaring the string variable.

[@chiteez_____1562]

Quiz solution: Since the array length = string length , therefore, the compiler will get no space to add ''\0' in the end and as a result it will not be considered as an string.

[@sumitkadam6773]

Cahr str[6]; is correct ,Cause we have a one more space for '\o'

[@phantomfury1608]

The word "hello" will create problem because it is a 5-letter word. In the code we have assigned the maximum value that the array can accommodate is up to 5. But while using string we have to denote '/0' in the array code to signify that the string ends here and not to print the garbage value further. So, array required to accommodate given string has to be number of characters in string +1 which is used to denote null character. Therefore, in the code shown, after accommodating the 5 characters of "hello" in the array, there will be no room for denoting null character which will create the problem in the code.

[@Flagshipcoding]

we have to use relative operator instead of assignment operator other we have to face error

[@vivekhalder2974]

the above snippet will create a problem because we are storing "hello" but '\0' character will also require a space which is not present as the size of the array is declared to be 1.
