This function allows an application to specify the initial value used by rand at program startup.Using this method of randomization, the program will use a different seed value on every run, causing a different set of random values every run, which is what we want in this case. The ...

Since the numbers are generated using an algorithm that uses a seed value, we do not consider the numbers generated to be actually truly random, rather, we call such numbers pseudo-random numbers. We often use the srand() function in conjunction with the rand() function. This function is...
We have a while loop for which the variable “k” is created and initialized with the value zero. The while loop runs through the size of the “RandString,” which is a random string and stores randomly created alphabets of string in a while loop. The variable “temp” is created here...

In this code, we generate five random floating-point numbers within the specified range of 10 to 100 using the traditionalrandfunction. To ensure varied sequences, we seed the random number generator with the current time. Inside the loop, we calculate each random float value by combining the...
