Question: Write a C++ statement that would print "The number is valid." if the variable grade is within the range of 0 through 100. Answer: ```if (grade >= 0 && grade <= 100) { cout << "The number is valid." << endl; }```

Step by step solution

(Step 1: Declare and Initialize)

First, let's declare and initialize a variable named grade: int grade = some_grade_value;

(Step 2: Check the grade's range)

Now, we will check whether the grade is within the range of 0 through 100 with the help of if statement and logical expressions.

(Step 3: Write the if statement)

Here's the if statement combined with the range check which prints the required message if the condition is true: ```cpp #include using namespace std; int main() { int grade = 45; // replace 45 with the desired grade value if (grade >= 0 && grade <= 100) { cout << "The number is valid." << endl; } return 0; } ``` Replace the grade value with the desired grade value. This program will output "The number is valid." if the grade is within the range of 0 through 100.
