Using const char*

I am writing some code in C++ to print a message using fprintf

Here is an example

Code:

void pr_desc(
    FILE*  stream,
    int       shift,
    const char*  desc) {

  const char*  format="%*s\e[0;37m%s\e[0m\n";
  fprintf(stream,format,shift,"",desc); 
}

I call it using

Code:

const char*  desc;  

desc="display susage";
pr_desc(stream, msgShift, desc); 

desc="prints some examples";
pr_desc(stream, msgShift, desc); 

desc="display this usage information";
pr_desc(stream, msgShift, desc);

I want to know how it is that I can change desc when I declared desc as const.

Why this const variable is not changing even after applying const_cast?

Hi In the following code, why the variable 'i' still retains the value 10 instead of 11? Why it is not possible to alter this variable's value? int main() { const int i = 10; *(const_cast<int*>(&i)) = 11; cout << i << endl; // Ans: 10 }
