For swapping two strings from one location to another location, we use strcpy() function.An array of characters (or) collection of characters is called a string.DeclarationFollowing is the declaration for an array −char stringname [size];For example, char string[50]; string of length 50 characters.InitializationUsing single character constantchar string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constantschar string[10] = "Hello":;AccessingThere is a control string "%s" used for accessing the string till it encounters ‘\0’strcpy ( )This function is used for copying source string into destination string.The length of the destination string is greater than or equal to the source string.The syntax ...
