A Value Of Type Const Char Cannot Be Used To Initialize An Entity Of Type Char

When you do "set = rndseq" you are assigning something that can't be changed (const char *) to something that can (char *). As a side note: It's actually very hard to pass a normal string via copy. to fix that, replace: grade="A" with grade='A'. Now you can see why passing a char* is very cheap. his comment is here

The two types of literals are not compatible: you need to supply a variable or a constant of a compatible type for the left side of the assignment. Maybe multi-core architectures have some shared cache but that doesn't really matter as you don't have to care about that. There's no distinction between warnings and errors in C89: the standard requires that "diagnostics" are issued for certain violations. share|improve this answer answered Nov 29 '13 at 22:16 Billie 2,28571737 add a comment| up vote 0 down vote C and C++ use double quotes to indicate "string literal", which is http://stackoverflow.com/questions/20294015/a-value-of-type-const-char-cannot-be-assigned-to-an-entity-of-type-char-c

I do not understand how one of the variables returned by a sub-routine can ever take a particular value. I don't think any compiler will continue compilation after this line. *s && !(((unsigned char)s[0]) & 0x80); s++) As far as I can tell, this is just a fancier and slightly Your compiler probably has a way to turn down the warning level; but it would be much neater (and certainly your boss would thank you) if you simply changed the code Assign Const Char* To Char* char& is a reference to a single char.

But optimization like using references or pointers (& and *) allow you to squeeze the last bit of performance out of your application.

So main's i is copied into func's i. this content Is that really the code ? Thank you very much, you are really helpful. On the other hand, "A" causes the compiler to write char(65) + char(0) into a part of the output program and then evaluates the expression "A" to the address of that A Value Of Type Void * Cannot Be Used To Initialize An Entity Of Type Char *

In particular, something like the following would work: strcpy(iname.name, "abc") (note that string literals are null terminated by the compiler and strcpy includes the \0) To make things (hopefully) more clear Convert Const Char* To Char* That's why it's not compatible. uhmm..

That's the idea behind it. Not the answer you're looking for? I want my program to read these cells and store them in A matrix. check over here But the semantics and syntax is a bit different.

And do this outside that FOR loop.

I am using aCC compiler:bash-2.04# aCC -VaCC: HP C/aC++ B3910B A.06.20 [May 13 2008]and I keep getting these casting related error messages. You are also copying the address (since both of these are pointers), and that will guarantee that "seq" can change whatever rndseq is looking at it. No new replies allowed. However, based on the error message, GetString returns a const char *.

Allocate an array long enough and use strcpy() to copy the content of the string literal into the array. If you see something like &variableName then it has a different meaning. It's important to remember because &nameOfSomeVariable is valid syntax but means sometimes entirely different.
