  • yes! It is possible to generate a random number using Rand() function which is predefined. 
    we can generate the random number series using the function called Rand().

    rand() and srand() in C/C++
     
    rand ()
     
    rand() function is used in C to generate random numbers. If we generate a sequence of random number with rand() function, it will create the same sequence again and again every time program runs. Say if we are generating 5 random numbers in C with the help of rand() in a loop, then every time we compile and run the program our output must be the same sequence of numbers.
    Syntax:
     
     int rand(void):
    returns a pseudo-random number in the range of 0 to RAND_MAX.
    RAND_MAX: is a constant whose default value may vary
    between implementations but it is granted to be at least 32767.
     
    // C program to generate random numbers
    #include <stdio.h>
    #include <stdlib.h>
     
    // Driver program
    int main(void)
    {
        // This program will create same sequence of
        // random numbers on every program run
     
        for(int i = 0; i<5; i++)
            printf(" %d ", rand());
        return 0;
    }
     
    NOTE: This program will create same sequence of random numbers on every program run.
    Output 1:
     
    453 1276 3425 89
     
    Output 2:
     
    453 1276 3425 89
     
    Output n:
