Convert string to char array
In programming, a string is a sequence of characters that is represented as a single data type. A char array, on the other hand, is an array of characters where each element in the array is a single character.
To convert a string to a char array, you need to break down the string into its individual characters and store them in an array of characters. This process is known as "string to char array conversion".
