In C$++,$ all values in an array must have the same data type$\mathrm{.}2.$ In a program that generates multiple random numbers, we need to call srand before each call to rand$\mathrm{.}3.$ If we create an array with an initialization list, we do not need to include a size declarator$\mathrm{.}4.$ A for loop is better than a while loop for a condition controlled loop$\mathrm{.}5.$ When a break statement is reached, the loop it is in is immediately exited.
