How do i prevent a C string input from the user from exceeding the capacity of the array? is this not possible?

int main()
{
char buffer[8];

printf("enter a string");
scanf(%s,&buffer);

return 0;
}

"%7s" instead of "%s". The field width will limit how many characters scanf reads and places into the array. Or better yet, use fgets for string input.

Use the function fgets().

char *fgets(char *s, int size, FILE *stream);

fgets is best option for taking string input.
