In C (and you've tagged this as C), that's pretty much the only way to initialize an array of char with a string value (initialization is different from assignment). When the array variable is initialized, you can assign values to the array. To initialize an array in C/C++ with the same value, the naive way is to provide an initializer list like We can create the string array in C (arrays of characters) using the 2d array of characters or an array of pointer to string. You can assign the list of objects during the declaration itself of separately. » Puzzles In this example the array indices 0 through 9 will be initialized with the characters and NULL character. char char_array[15] = "Look Here"; . Better way to use is collection when the length is not known. char c[] = "abcd"; char c[50] = "abcd"; char c[] = {'a', 'b', 'c', 'd', '\0'}; char c[5] = {'a', 'b', 'c', 'd', '\0'}; Let's take another example: char c[5] = "abcde"; Here, we are trying to assign 6 characters (the last character is '\0') to a char array having 5 characters. » C# There are two ways to initialize an array. » Java Similarly, the array of Strings is nothing but a two-dimensional (2D) array of characters.

Strings are actually one-dimensional array of characters terminated by a null character '\0'. You can assign the list of objects during the declaration itself of separately. 1. Just like any other array, you can put the array size inside the [] of the declaration: char char_array[15] = "Look Here"; Make sure that the size you put inside [] is large enough to hold all the characters in the string, plus the terminating NULL character. For example, int[] rank = new int[5]; You can assign values to an array at the time of declaration.
