Type a statement using srand () to seed random number generation using variable seedVal. Then type two statements using rand () to print two random integers between (and including) 0 and 9. End with a newline. Ex: #include #include / / Enables use of rand () #include / / Enables use of time () using namespace std: int main () { int seedVal = 0 / * Your solution goes here * / return 0: }

Replace / * Your solution goes here * / with the following code segment

srand (seedVal);

cout<
cout<
Explanation:

From the code segment, the seedVal has already been declared and initialized to 0; The next step is to seed it as random number using srand.

The first line of the code segment in the Answer section "srand (seedVal); " is used to achieve that task.

Having done that, the next step is to write statements to generate the two random numbers using rand ();

When generating random numbers, two things are to be noted;

The lower bound; L The upper bound; U

Here, the lower bound is 0 and the upper bound is 9;

C rand () function uses the following syntax to generate random numbers

rand () % (int) (U - L + 1) + L

Where U = 9 and L = 0

Replacing U and L with there respective values; the syntax becomes

rand () % (int) (9 - 0 + 1) + 0

So, the two print statements will be written as

cout<
Also, the question states that, each print statement be ended with a new line;

So, the print statements will be

cout<
Alternatively, by solving (9 - 0 + 1) + 0; the statements can be written as

cout<
Conclusively, the complete statements is as follows;

srand (seedVal);

cout<
cout<
or

srand (seedVal);

cout<
cout<
