Analyze the following C++ programming snippet
#include
using namespace std;
int main()
{
unsigned int vals[10];
size_t which;
unsigned int square;
for (size_t i = 0; i < 10; i++ )
vals[i] = (i+1)*(i+1);
cout << "Please type a number: ";
cin >> which;
square = vals[which-1];
cout << "The square of " << which << " is " << square << endl;
return 0;
}
• Are there instances were input is requested from an end user? Provide an explanation to justify your answer.
• Evaluate the code and identify possible flaws with the code in the context of accepting input from users.
• Analyze the output provided and provide an explanation for the result displayed.
• Does CPP check capture all the possible problems with the code. Provide an explanation to justify your answer.
• Provide recommendations on how the flaws in the program can be fixed and how this can help with security.
Explanation / Answer
1. cin takes the input from the user. So, there is only one instance where input is taken from the user.
2. The input taken from the user should be greater than zero and less than 11. This check is not there.
3. The program saves the squares of first ten numbers in an array. It takes input from the user to display the square of any number between 1 to 10.
4. CPP check will provide only compile issues. It doesn't check any logical errors like checking whether the input is in the range of length of array.
5. First, make sure there are no compilation issues and then check the logic like checking the conditions while accepitng user input etc.
