[ad_1] std::vector<int> b = a; will this creates b as a copy (new object with same contents) of vector a or as a reference to it? that create b as a new vector being a copy, so b.append(1); does not change a [ad_2] solved Std::vectors – copying vs creating a reference

[ad_1] The switch statement jumps to the case that matches, and continues processing from there until it sees a break. Since there are no breaks in that code, it starts at case 1, outputs 1, and then continues with case 2 and outputs 2. Although it’s rare, sometimes this “fall through to the next case” … Read more
[ad_1] (I did that answer while R 0x… and W 0x… was given on the same line rather than two) If you are sure each line of the file contains R<space>0x…<space>W<space>0x… then you can do int main() { FILE * fp = fopen(“in”, “r”); if (fp == NULL) { puts(“cannot open ‘in'”); return -1; } … Read more
[ad_1] As Scott said, result is defined inside the flip function. I haven’t really used async before, but probably this will work for you. Take out the return statement Tab the following lines. elif message.content.startswith(config.prefix + ‘coinflip’): result = random.randint(0, 1) if result == 1: print(‘Heads!’) await client.send_message(message.channel, content=”Heads!”) else: print(‘Tails!’) await client.send_message(message.channel, content=”Tails!”) 1 … Read more

In order to have the C/C++ compiler check that you’ve defined your callback function correctly, and to simplify usage of such callbacks, a typedef is often used. … Read more
[ad_1] The std::vector<float> class is a class and not a pointer. I think your teacher wants to discourage you from using the c-style arrays: float* array = new float[200]; This might be because using this you have to remember to delete them later: delete[] array; The vector<float> will handle this for you. Plus gives you … Read more

[ad_1] If the float is uninitialized when the member function is called, the default value used in the prototype will be assigned to it. If that float has a value when the member function is called, the default is ignored. [ad_2] solved Object calls function without arguments to a function that requires an argument [closed]
