    C library - rand() function



    The C stdlib library rand() function is used to returns the pseudo-random number in the range of 0 to RAND_MAX.

    RAND_MAX represents the maximum value that can be returned by the rand() function, and their default value may vary depending on the implementation of the c library.

    But it is granted to be at least 32767.

    Syntax

    Following is the C library syntax of the rand() function −

    int rand(void)

    Parameters

    This function does not accepts any parameters.

    Return Value

    This function returns an integer value that is lies between 0 to RAND_MAX.

    Example 1

    In this example, we create a basic c program to demonstrate the use of rand() function.

    #include <stdio.h> #include <stdlib.h> int main() { // store the random value int rand_value = rand(); // display the random value printf("Random Value: %d\n", rand_value); return 0; }

    Following is the output, −

    Random Value: 1804289383

    Example 2

    The below c program used to display the random number within a range using the rand() function.

    #include <stdio.h> #include <
