to randomly generate a number in a range, you can define a random (int number) function in the macro definition, and then call the random () function directly inside main (): For example: Randomly generate 10 0~100 numbers: #include #include #define RANDOM (x) (rand ()%x) void Main () { for (int x=0;x printf ("%d/n", Random (100)); }

Problemconsider a function which, for a given whole number N, returns the number of ones required when writing out all numbers between 0 and N. for example, F (13) = 6. notice that F (1) = 1. what is the next largest N such that F (n) = n? Algorithm idea: calculate the number of 1 in each number cyclically. If F (n) =

member of the struct, and the size of the structure returned by SIZEFO does not include the memory of the flexible array. Flexible array members can be used not only for character arrays, but also for arrays of elements of other types. Structures that contain flexible array members are dynamically allocated with the malloc () function, and the allocated memory should be larger than the size of the structure to accommodate the expected size of the flexible array.The C + + standard specifies that
