Furthermore, Char arrays are faster, as data can be manipulated without any allocations. Edurekas Java J2EE and SOA training and certification course is designed to train you for both core and advanced Java concepts along with various Java frameworks like Hibernate & Spring. In Java, array is an object of a dynamically generated class. strstr(s1,s2); this finds the first occurrence of string s2 in the string s1 and the pointer points to the string s2 in the string s1. Declaration of a char array can be done by using square brackets: char[] JavaCharArray; The square brackets can be placed at the end as well. If you want to incorporate the conversion process (text -> hex include file) directly into your build the hexdump.c tool/library recently added a capability similar to xxd's -i option (it doesn't give you the full header - you need to provide the char array definition - but that has the advantage of letting you pick the name of the char array): http://25thandclement.com/~william/projects/hexdump.c.html. -1 because the presence of this answer is slightly encouraging people to waste their time trying something that doesn't work. strchr(s1, ch); these functions find the first occurrence of the given character ch in the string s1 and the pointer points to this character in the string.

What is for loop in java and how to implement it? First: The declaration and definition don't match since the declaration specifies that the function takes two chars while the definition specifies that the function takes two char*: You need to make the declaration the same as the definition: but, in order to copy from string literals, you need to make the first argument take a const char* since string literals consists of const chars. There are however not 50 chars in "CHAMPAGNE" so trying to copy that many will make your function access "CHAMPAGNE" out of bounds (with undefined behavior as a result).
