How can I get the character from the user in the console and then display it?

I wrote below code but it doesn't work and shows error after inputting the line

char Fname[20];
printf("Enter name:");
scanf_s("%19s", Fname);
Printf("%s\n",Fname);

      

        
        
        
      

    

Error: Exception thrown at 0x0F17DDf4

thanks for the help
