Question

Find the output of the following c code-
 

main()
{
    char *ptr="gatebuddy";
    *(ptr)++;
    ptr++;
    printf("%s\n",ptr);
}

Answer 1

char *ptr="gatebuddy"; // ptr is a pointer variable pointing to a string literal 'gatebuddy'. C by default adds a null character (\0) at the end of any string literal.

*(ptr)++;      // ptr point 2nd element of string literal 'gatebuddy' as postincrement has higher precedence than indirection. 

Ref: http://en.cppreference.com/w/c/language/operator_precedence

ptr++;       // ptr point 3rd element of string literal 'gatebuddy'

printf("%s\n",ptr);  //it ll print all character of string from 3rd element to that index where null character is stored.

i.e.   it will print tebuddy
