How to generate pseudorandom numbers using power generator containing seed in C

The power generator is a method for generating pseudorandom numbers. To use the power generator, parameters 𝑝 and 𝑑 are specified, where 𝑝 is a prime, 𝑑 is a positive integer such that 𝑝∤𝑑, and a seed 𝑥0 is specified. The pseudorandom numbers 𝑥1,𝑥2,⋯ are generated using the recursive definition '''𝑥𝑛+1 = 𝑥𝑛𝑑 (𝒎𝒐𝒅 𝑝)'''. Write a program to generate pseudorandom numbers using power generator method and test your program to (a) find the sequence of pseudorandom numbers generated by the power generator with 𝑝 = 3,5,& 7 (choose the integer 𝑑 accordingly) and take the seed 𝑥0=2

I did solved this problem in java but I am having trouble in doing that in C.
