C++ program to generate random number

Last Updated : 03 Jan, 2018

The below implementation is to generate random number from 1 to given limit. The below function produces behavior similar to srand() function. Prerequisite : random header in C++ | Set 1(Generators)

CPP

// C++ program to generate random number
#include <bits/stdc++.h>
using namespace std;

// Function with return random number from 1 to
// given limit
int randomNoGenerator(int limit)
{
    // uniformly-distributed integer random number
    // generator that produces non-deterministic
    // random numbers.
    random_device rd;

    // A Mersenne Twister pseudo-random generator
    // of 32-bit numbers with a state size of
    // 19937 bits.
    mt19937 gen(rd());

    // Uniform distribution
    uniform_int_distribution<> dis(1, limit);
    return dis(gen);
}

// Driver Code
int main()
{
    int limit = 100;
    cout << randomNoGenerator(limit) << endl;
    return 0;
}

Generate Random Double Numbers in C++

Double is a data type just like a float but double has 2x more precision than float. One bit for the sign, 11 bits for the exponent and 52* bits for the value constitute the 64-bit IEEE 754 double precision Floating Point Number known as "double." Double has 15 decimal digits of precision. In this a

How to Seed a Random Number Generator in C++?

In C++, seeding a random number generator is important for generating different sequences of random numbers on each program run. This process consists of initializing the generator with a starting value, known as a seed. This ensures the randomness and unpredictability required for various applicati
