object-C练习小程序(3)

在Object-C中求两个数得最大公约数，代码如下：

#import <Foundation/Foundation.h>

int main(int argc,const char * argv[])

{

    @autoreleasepool {

        

       unsigned int u =0;

       unsigned int v =0;

       unsigned int temp =0;

        

        NSLog(@"Please type in two nonnegative integers.");

       scanf("%u%u", &u, &v);

        

        

       while (v != 0) {

            temp = u % v;

            u = v;

            v = temp;

        }

        

        NSLog(@"Their greatest common divisor is %u.", u);

        

    }

   return 0;

}

程序运行结果如下：

2014-04-07 10:52:28.380 Object-Test[602:303] Please type in two nonnegative integers.

40 80    //此处输入40 80

2014-04-07 10:52:36.206 Object-Test[602:303] Their greatest common divisor is 40.

Program ended with exit code: 0
