Difference between string size in Standard C and C++

Question

I compiled the following code in C Standard and C++:

#include <stdio.h>
#include <string.h>

char string[5] = "hello";

int main(void)
{

   printf("string tem %lu bytes\n", sizeof(string));

   for (int i = 0; i < 6; i++)
   {
      printf("string[%d]: %d \n", i, string[i]);
   }

   return 0;
}

In Standard C it compiles normally, but in C++ it gives error when compiling.

What is the difference between C and C++ to give this error?

output in C++:

entradas.cpp:4:18: error: initializer-string for array of chars is too long [-fpermissive]
    4 | char string[5] = "hello";
      |                  ^~~~~~~

Intellisense vs Coded Warning:

um valor de tipo "const char [6]" não pode ser utilizado para inicializar  uma entidade do tipo "char [5]"C/C++(144)

Complementing, I compiled smoothly in standard C, and in c++ using the variable declaration in this way:

char string[5] = {'h','e','l','l','o'};

I used vsCode (code Runner) and Replit.
