Midterm will be between 5-6:30 on a T or Th. email me at once if that won't work.

If you have a code question, submit via turnin and then email me. Be sure to let me know to look.

printf - Full control over printing
- 1st argument is a string. 
  * Subsequent arguments are designated in that string using format specifiers (start with %)
- Total arguments is 1 + # of format specifiers in the format string.
- Examples: 
   To print a real number in 12 spaces with 3 after the decimal point:  %12.3f
   To give a field width to an int or char or string: %8d or %8s   
     * Unless otherwise specified, items print right justified. 
     * Field widths are minimal


Comparing Strings
- Based on character comparisons
  * Two strings are equivalent if: 
	corresponding characters of each string are identical to the end of both strings, 
            i.e. both strings are also the same length
- C++ has overloaded relational operators for strings 
- C-strings: Must use string.h routine strcmp
   "ABCD" != "ABCDE" because the terminating null char in the first string matches agains 'E' in the 2nd string
   Examples:
     strcmp("ABC","ABC") returns 0
     strcmp("ABCD","ABCDE") returns a negative number

int strcmp(char *s1, char *s2)
{int idx=0;
 while (s1[idx]!='\0' && s2[idx]!='\0' && s1[idx]==s2[idx])
   idx++;
 if (s1[idx]==s2[idx]) 
   return(0);
 if (s1[idx]<s2[idx])
   return(-1);
 return(1);
}


int strcmpPtr(char *str1,char *str2)
{ for ( ;*str1 && *str2 && *str1 == *str2;str1++,str2++);
  return(*str1-*str2);    
}

With a C-string, the assignment operator can NOT be used to copy strings. 

Must use strcpy, e.g.  strcpy(s1,s2)
