    Anything can be done with inbuilt C functions please?
    I have no knowledge of random number generators! So cannot implement this without theoretical knowledge!

    srand() and rand() are part of the C standard library and can be found in <stdlib.h>.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
