Assigning a char array to another char arrayThis tip submitted by Brian Plummer on 2010-12-26 17:05:00. It has been viewed 25504 times.Rating of 4.3 with 69 votes When a char array is defined it can be initialised with a string constant, creating a C string: unsigned char String1[20] = "Hello world"; unsigned char String2[20]; To copy String1 char array to String2 char array, you cannot simply assign the whole array to it, it has to be copied one character at a time within a loop, or use a string copy function in the standard library. However, when string arrays are within a structure they can be simply assigned: struct StringStruct { unsigned char String[20]; }; Struct StringStruct String1 = {"Hello world"}; Struct StringStruct String2; String2 = String1; Now String2.String array is equal to String1.String array. Of course, if you're working in C++, it's much easier to simply use std::string which overloads the assignment operator to make this simple. More tips Help your fellow programmers! Add a tip! |
