My code for Exercise 4

[darrinaltman]

I know this isn't the most efficient and obviously not the best way to solve this but here is how I approached it.  Please critique.  All comments welcomed, especially critical comments.


#import <Foundation/Foundation.h>

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

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    double x;
    double result1;
    double result2;
    double sum;
   
    x = 2.55;
    result1 = 1;
    result2 = 1;
   
    for (int i = 0; i < 3; i++) {
        result1 *= x;
    }
    for (int j = 0; j < 2; j++) {
        result2 *= x;
    }
   
    sum = 3 * result1 - 5 * result2 + 6;
    NSLog(@"\nThe answer is: %g.", sum);

    [pool drain];
    return 0;
}
