Generate random number c++

Returns a pseudo-random integral number in the range between 0 and RAND_MAX

This number is generated by an algorithm that returns a sequence of apparently non-related numbers each time it is called. This algorithm uses a seed to generate the series, which should be initialized to some distinctive value using function srand.

RAND_MAX is a constant defined in <cstdlib>

A typical way to generate trivial pseudo-random numbers in a determined range using rand is to use the modulo of the returned value by the range span and add the initial value of the range:

v1 = rand() % 100;         // v1 in the range 0 to 99
v2 = rand() % 100 + 1;     // v2 in the range 1 to 100
v3 = rand() % 30 + 1985;   // v3 in the range 1985-2014 

Notice though that this modulo operation does not generate uniformly distributed random numbers in the span (since in most cases this operation makes lower numbers slightly more likely).

Oglinditul unui numar

Oglinditul unui numar are ca scop afisarea inversului unui numar dat.

Ex: 384629–>>926483

Algoritmul se bazeaza pe faptul ca aflarea cifrelor unui numar se realizeaza incepand cu cifra unitatilor,acestea eliminandu-se pe rand,pana cand numarul dat devine egal cu 0.

Permutarea cifrelor

Să se scrie o funcție C++ care să realizează permutarea circulară spre stânga a cifrelor unui număr natural. Numărul este transmis prin intermediul unui parametru care se întoarce din funcție modificat. Soluţia propusă va conţine doar definiţia funcţiei cerute. Prezenţa în soluţie a altor instrucţiuni poate duce erori de compilare sau de execuţie care vor avea ca efect depunctarea soluţiei.

Utilities like Telnet and remote control programs like Symantec’s PC Anywhere let you execute programs on remote systems, but they can be a pain to set up and require that you install client software on the remote systems that you wish to access. PsExec is a light-weight telnet-replacement that lets you execute processes on other systems, complete with full interactivity for console applications, without having to manually install client software. PsExec’s most powerful uses include launching interactive command-prompts on remote systems and remote-enabling tools like IpConfig that otherwise do not have the ability to show information about remote systems.

Note: some anti-virus scanners report that one or more of the tools are infected with a “remote admin” virus. None of the PsTools contain viruses, but they have been used by viruses, which is why they trigger virus notifications.
