Question
What is the output of the following code?
char str[] = "hello";
printf("%c\n", str[1]);
Solution
The output of the code will be 'e'.
Here's the step by step explanation:
-
The code declares a character array
str[]and initializes it with the string "hello". -
In C and C++, strings are actually one-dimensional array of characters terminated by a null character '\0'. So the string "hello" is stored in the array like this: 'h', 'e', 'l', 'l', 'o', '\0'.
-
Array indexing in C and C++ starts from 0. So,
str[0]is 'h',str[1]is 'e',str[2]is 'l', and so on. -
The
printffunction is used to print the character at index 1 of the array, which is 'e'. So, 'e' will be the output of the code.
