int totalcount = 0; // start a counter
for (NSString *n in names){ // go through propernames dictionary
for (NSString *o in words){// go through the words dictionary
if ([o isEqualToString:[n lowercaseString]]){ // if the lowercase version of the propername is the same as the regular word
totalcount++; // increment the counter
NSLog(@"%@ AND %@\n", n, o); // print out the matching propername and word
}
}
}
NSLog(@"the total number of matches = %i", totalcount); // what was the total count
the trouble i am having is that my total count is 294 and i get an extra AND
somehow the loop is going through one extra time.
the only explanation i can come up with is that the two dictionary files have and extra line at the end that my code is reading as the same and outputting them.
this is my current output:
2014-02-25 19:56:13.153 intNames[1625:303] Win AND win
2014-02-25 19:56:13.451 intNames[1625:303] Wolf AND wolf
2014-02-25 19:56:13.652 intNames[1625:303] Woody AND woody
2014-02-25 19:56:13.806 intNames[1625:303][color=#FF0000] AND [/color]
2014-02-25 19:56:13.806 intNames[1625:303] the total number of matches = [color=#FF0000]294[/color]
thanks.
any ideas if i want the program to skip over those?
would something like this work?
like if (the string is a " " then skip it)
and put my original if statement as an else?
i guess my real question is how come other people’s programs didn’t count the " " even though they didn’t account account for it?
ok. i tried to get rid of the extra entry that is just a space by using an if statement before comparing the two strings.
if (![n isEqualToString:@" "])
but i still get the same output.
2014-02-26 19:52:24.358 intNames[4127:303] Woody AND woody
2014-02-26 19:52:24.538 intNames[4127:303] AND
2014-02-26 19:52:24.538 intNames[4127:303] the total number of matches = 294
I had exactly same problem, thanks Ibex10 for the lastObject tip. Here is my code for the solution.
[code]#import <Foundation/Foundation.h>
int main(int argc, const char * argv[])
{
@autoreleasepool {
// Read in at the files and break contents into array
NSString *nameString = [NSString stringWithContentsOfFile:@"/usr/share/dict/propernames" encoding:NSUTF8StringEncoding error:NULL];
NSArray *names = [nameString componentsSeparatedByString:@"\n"];
NSString *wordString = [NSString stringWithContentsOfFile:@"/usr/share/dict/words" encoding:NSUTF8StringEncoding error:NULL];
NSArray *words = [wordString componentsSeparatedByString:@"\n"];
int wordcount = 0; // used as a match counter
NSString *erroneous = [words lastObject];// to get red of newline character in count which is last object in each array
// use nested for loops to compare the proper names to the words from the word file. As the word file also contains all the Proper names as well, The proper names are 1st converted to lower case so that we only get matches to words and not the proper names.
// loop construction importanta outer loop has significantly less items in it than inner loop.
for (NSString *nameToCompare in names) {
NSString *lowerCaseName = [nameToCompare lowercaseString];
for (NSString *wordToCompare in words) {
// finds matches returning an NSComparison result called match
NSComparisonResult match = [wordToCompare localizedCompare:lowerCaseName];
if (wordToCompare != erroneous ) { // removes erroneous last array item
if (match == NSOrderedSame) { // When wordToCompare returns NSOrderedSame means that the 2 items being compared are completly equal
wordcount++;
NSLog(@"Match Count %i: %@", wordcount, wordToCompare);
break; // this makes the program more efficient as once it finds the proper name breaks out of for loop and starts checking for next proper name
}
}
}
}
// NS Log provides the summary information below
NSLog(@" The propernames file contains %lu names", [names count]);
NSLog(@" The words file contains %lu words", [words count]);
NSLog(@"Total Proper names that are words found is %i", wordcount);
}
return 0;
