Question

What is the output of the following code segment and why?

int main(void)
{
    // Find the output of the following and explain it:
    char name[] = "Hello";
    name[2] = '\0';
    printf("%s\n", name);

    return 0;
}

why answer is he?

Answer 1

Strings in c ends with a special character '\0'

In other words, '\0' indicates the end of the string

char name[] = "Hello";
After this line, name is "Hello"
Internally It stores name as "Hello\0"

name[2] = '\0';
After this line
It changes name as "He\0lo\0"

So, it means string ends after "He"

So, output of the code is
He

Output :

He
