You can read the tutorial here. It looks at the different ways memory is used in a C program. Do you know for instance what BSS is and when it is used compared to Data or where variables in a function declared static are held in memory?

I also tried overwriting a text literal out of curiosity to see what happens. Here’s the source:

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

char* name="My name is David";
int main()
{    
    strcpy_s(name,10, "New name");
    printf("Name = %s\n", name);
    return 0;
}

 
As you’d expect it blew up”
