Why is const-correctness specific to C++?

Question

Disclaimer: I am aware that there are two questions about the usefulness of const-correctness, however, none discussed how const-correctness is necessary in C++ as oppos

Answer 1

For example you have a funcion:

void const_print(const char* str)
{
    cout << str << endl;
}

Another method

void print(char* str)
{
    cout << str << endl;
}

In main:

int main(int argc, char **argv)
{
    const_print("Hello");
    print("Hello");        // syntax error
}

This because "hello" is a const char pointer, the (C-style) string is put in read only memory. But it's useful overall when the programmer knows that the value will not be changed.So to get a compiler error instead of a segmentation fault. Like in non-wanted assignments:

const int a;
int b;
if(a=b) {;} //for mistake

Since the left operand is a const int.
