int av_cmp_q(AVRational a, AVRational b); 0 if a == b 1 if a > b -1 if a < b
Here is what the above code is Doing:
1. It's creating a new AVRational structure called a.
2. It's creating a new AVRational structure called b.
3. It's comparing the two structures.
factorial(N){ if(N
class A { //statements of class A }; class B:public A { //inherting class B from class A //statements of class B }; Here is what the above code is Doing: 1. Class A is the base class. 2. Class B is the derived class. 3. Class B inherits from class A. 4. Class A…
// Inserting at start vector_name.insert(vector_name.begin(), element_to_be_inserted); // Inserting after xth element vector_name.insert(vector_name.begin()+(x-1), element_to_be_inserted); // Inserting at last vector_name.push_back(element_to_be_inserted); Here is what the above code is Doing: 1. Inserting at start vector_name.insert(vector_name.begin(), element_to_be_inserted); 2. Inserting after xth element vector_name.insert(vector_name.begin()+(x-1), element_to_be_inserted); 3. Inserting at last vector_name.push_back(element_to_be_inserted);
sf::RenderWindow window(sf::VideoMode(900,900),”My window”); //VideoMode is an object who tell to the window which size take Here is what the above code is Doing: 1. We create a window object called window. 2. We pass two parameters to the constructor of the window object. 3. The first parameter is a sf::VideoMode object. This object holds information…
bool isPowerOfTwo(int n) { return n > 0 && !(n&(n-1)); } Here is what the above code is Doing: 1. n > 0 checks if n is positive. 2. !(n&(n-1)) checks if n is a power of 2. How does this work? Let’s take the example of 4. 4 in binary is 0b100. n-1 is…
// Remember, the data type of the member variable needs to be unsigned, // as you only need to store 0 and 1. typedef struct foo { unsigned x:1; } foo; Here is what the above code is Doing: 1. We are creating a struct called foo. 2. We are creating a member variable called…
