Join them; it only takes a minute: Sign up Why array type object c function return string is not modifiable? up vote 6 down vote favorite 4 It is stated here that The term modifiable lvalue is used to emphasize that the lvalue allows the designated object to be changed as well as examined. The following object types are lvalues, http://www.microchip.com/forums/m301018.aspx but not modifiable lvalues: An array type An incomplete type A const-qualified type A structure or union type with one of its members qualified as a const type Because these lvalues are not modifiable, they cannot appear on the left side of an assignment statement. Why array type object is not modifiable? Isn't it correct to write int i = 5, a[10] = {0}; a[i] = 1; ? And also, what is an incomplete type? c arrays lvalue share|improve this question asked Jul 16 '13 at 21:35 http://stackoverflow.com/questions/17687429/why-array-type-object-is-not-modifiable haccks 67.9k1788162 I think change the type mean go from int a[10] to double a[10] –Ran Eldan Jul 16 '13 at 21:37 2 There's a difference between a = value and a[i] = value –Tim Cooper Jul 16 '13 at 21:37 @TimCooper; Please elaborate your answer. –haccks Jul 16 '13 at 21:38 add a comment| 5 Answers 5 active oldest votes up vote 13 down vote accepted Assume the declaration int a[10]; then all of the following are true: the type of the expression a is "10-element array of int"; except when a is the operand of the sizeof or unary & operators, the expression will be converted to an expression of type "pointer to int" and its value will be the address of the first element in the array; the type of the expression a[i] is int; it refers to the integer object stored as the i'th element of the array; The expression a may not be the target of an assignment because C does not treat arrays like other variables, so you cannot write something like a = b or a = malloc(n * sizeof *a) or anything like that. You'll notice I keep emphasizing the word "expression". There's a difference between the chunk of memory we set aside to hold 10 integers and the symbols (expressions) we use to refer to that chunk of memory. We can refer to it with the expression a. We can also create a pointer to that array: int (*ptr)[10] = &a; The expression *ptr

I have built a three wire LCD interface and would like to write some messages on it. I can get the ADC results on the screen if I use the in c itoa function like this: Code (text): itoa(result,output);//Convert ADC result to string while(output[i]) nybbleOut(output[i++]); i = 0; However, I can not assign a literal value to the string like: Code (text): output = "Hello, world"; I have the output assigned as a character array. Why can't I error 1153 cannot just assign the string like above? What does "const rom char*" mean? I tried looking inot the user's guide, but it does not explain it well enough for me to understand.
