Answer 1

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[])
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys:
                            [NSNumber numberWithInt:8], @"c",
                            [NSNumber numberWithInt:5], @"objective c",
                            [NSNumber numberWithInt:3], @"c++",
                            [NSNumber numberWithInt:6], @"python",
                            [NSNumber numberWithInt:2], @"java", nil];
 
    NSDictionary *dict2 = [NSDictionary dictionaryWithObjectsAndKeys:
                            [NSNumber numberWithInt:1], @"php",
                            [NSNumber numberWithInt:4], @"rust",
                            [NSNumber numberWithInt:7], @"dart", nil];

    NSMutableDictionary *mergedDict = [[NSMutableDictionary alloc] initWithDictionary:dict1];
    [mergedDict addEntriesFromDictionary:dict2];
    
    NSLog(@"%@", mergedDict);

    [pool drain];
    
    return 0;
}

run:

{c = 8; "c++" = 3; dart = 7; java = 2; "objective c" = 5; php = 1; python = 6; rust = 4; }
