Calculate StringLength in MacOS

Sushant — Fri, 04 Feb 2011 10:43:14 +0000

This is the very simple example, in this program we will see how to calculate string length in MacOS.

Step 1: Create a Cocoa Application from Mac OS X . Give the application name “StringsLength”.

Step 2: Xcode automatically creates the directory structure and adds essential frameworks to it. You can explore the directory structure to check out the content of the directory.

Step 3: xpand the Other Sources folder, then you can see one file “main.m”. We need to make changes in this file.

Step 4: Open the main.m file and make the following changes in the file.

#import 
 int main(int argc, char *argv[])

 {

        char s1[250];

        char s2[250];

        printf("Enter string s1:\n");

        scanf("%s",&s1);

        printf("Enter string s2:\n");

        scanf("%s",&s2);

        if(strlen(s1) == strlen(s2))

        printf("Length of string s1 is equal to length of string s2\n");

        else if(strlen(s1) < strlen(s2))

        printf("Length of string s1 is less than length of string s2\n");

        else

        printf("Length of string s1 is greater than length of string s2\n");

        return NSApplicationMain(argc,  (const char **) argv);

}

Step 5: Now compile and run the example and see the output on the console.

Make $400 to $5000 DAILY from Ad Revenues With Your Free App

vishy — Thu, 05 Aug 2010 09:37:01 +0000

The iPhone Apps get-rich-quick landscape is best suited for one of two people development shops. However, some companies are also making good revenues – specifically from in-app advertising.

In the report below, AdWhirl says that top apps can make $400 to $5,000 per day on ads. The average CPM works out to around $2 per 1000 impressions. It may not look impressive but its substantially better than the CPM rates at Facebook or MySpace apps.

However – These apps are from the most popular section on the app store… listing within the top 100 free apps. This is what is causing a problem for small developers. You need to crack into the top 100 if you want to get to the $400 daily revenue target.

An Average of 10 Apps Downloaded Per Month by iPhone and Android Users

vishy — Sun, 02 Aug 2009 04:50:11 +0000

iPhone and Android users are downloading approximately ten new apps every month, according to mobile ad network AdMob’s latest Mobile Metrics Report for July 2009.

However, surprisingly owners of Apple’s iPod touch, are downloading an average of 18 apps per month – beating iPhone and Android users. Meanwhile, users who regularly download paid apps are spending around $9 a month on five paid downloads.

The report goes on to say that more than half of iPhone and Android users spend 30 minutes plus, a day using apps on their devices. Also, more than 90% browse and search for apps on their devices – which is not very surprising for Android, because it does not yet have an associated web-store.

AdMob’s report also goes on to compare the different smartphone platforms in terms of usage of its ad network. In July, iPhone accounted for 60%, followed by BlackBerry handsets with 13%, and Android devices with 12%.

VCs Continue to Invest more and more in iPhone Startups

vishy — Tue, 07 Jul 2009 06:13:24 +0000

A recent study and data by the folks at Chubbybrain shows that VCs have invested over $100 million into companies and startups working in the iPhone space. 17 companies formed part of th study and some interesting stats are shown below. The study limited the scope of this study to startups whose core functionality and capability is centered on the iPhone.

Interestingly there seems to be a co-relation between the number of iPhones sold and the amount of VC money being invested – with both numbers growing relatively together over a span of time.

You can see all the fancy stats and graphs with some interesting trends here.
