Guys can you tell me to allocate dynamic memory in c for string
Have you heard about malloc?

Yes
Mity
When i use malloc and run program it says segmentation error
Mity
malloc for Int work fine

Well, we should see your code, and get more details about the error (in which line, or something).
How have you used malloc?

#define MANY(T,N) (T*)malloc(sizeof(T)*(N))
char* str=MANY(char,80);
strcpy(str,"hello world!");
puts(str);
Mity
Okay... I'll send the codes tomorrow

Maybe... you did not allocate enough memory?
For int you did something like malloc(sizeof(int))
For string, you should multiply by the number of characters you want to allocate, like malloc(sizeof(char) * 10)

For char i think it shoud be added by 1 instead of multiplying by 10
Raz
If you want 10 characters, including the 0 at the end, you should multiply the size of char by 10

You're so funny

#define new(t) (t*)malloc(sizeof(t))
int* funny = new(int);

#define new(t) (t*)malloc(sizeof(t))
int* funny = new(int);
Well, so what? If you know nothing about c++, it's better to say nothing

C++ is not only about new/delete

If you think so — you are a noob
if( c ){
__autofree char* world = strdup("hello");
puts(world);
}

Now show us some metaprogramming in C

If you want to think so, programming languages do not exist and are all handy macro systems around binary

compiles to c, but it's not a pain in the ass :^)

it's like c but without the undefined behaviour

Well I would like to know how it enforces endianness across platforms

Well
There's a cool language called C++
Compiles to machine code
And every three years it becomes less pain in the ass
I prefer this
