#includetypedef struct test1 { int a; char b; } TOTO; std::vector _v; _v.push_back((TOTO){10, 'a'}); _v[0].a = 101;
Here is what the above code is Doing:
1. Define a struct called TOTO with two members: an int and a char.
2. Define a vector of TOTO’s called _v.
3. Push a TOTO onto the vector.
4. Change the first element of the vector.
boost::filesystem::absolute(path).string() Here is what the above code is Doing: 1. We’re using the boost::filesystem::path class to represent the path. 2. We’re using the boost::filesystem::absolute() function to convert the path to an absolute path. 3. We’re using the boost::filesystem::string() function to convert the path to a string.
Solidity is the primary language on Ethereum as well as on other private blockchains running on platforms that compete with Ethereum, such as Monax and its Hyperledger Burrow blockchain, which uses Tendermint for consensus. Here is what the above code is Doing: 1. We’re defining a new contract called Greeter. 2. The constructor function is…
int pow(int base, int exp) { if(exp < 0) return -1; int result = 1; while (exp) { if (exp & 1) result *= base; exp >>= 1; base *= base; } return result; } Here is what the above code is Doing: 1. If the exponent is negative, return -1. 2. Initialize result as…

#include std::map map; map[10] = “Hello”; map[1] = “boys”; map[901] = “girls” Here is what the above code is Doing: 1. We’re creating a map that maps size_t to std::string. 2. We’re adding three elements to the map. 3. We’re accessing the element with key 10. 4. We’re accessing the element with key 1. 5….
