WebDec 12, 2024 · You can use the rand () and srand function to generate numbers between 0 and 1. Since the numbers between 0 and 1 will be in decimals, you must cast the result to either float or double, just like you did in the previous example. If you don’t typecast the result, it will be converted to an integer; hence, the output will be 0.
