Use the rand function   http   www cplusplus com reference clibrary cstdlib rand   Quote   A typical way to generate pseudo-random numbers in a determined range using rand is to use the modulo of the returned value by the range span and add the initial value of the range     value   100   is in the range 0 to 99   value   100   1   is in the range 1 to 100   value   30   1985   is in the range 1985 to 2014
