Can anyone help me with these coding questions
Exercise 3. Use the program shell below to implement a program called SumDigits. When completed, program SumDigits prompts for and reads a one-digit number, then adds the numbers from zero to the number, inclusive, and prints the sum. // Program SumDigits prompts for and reads a one-digit number. // Values between 0 and the digit (inclusive) are summed. #include <iostream> using namespace std; int main () // Loop-control variable // Running sum int counter; int sum; int digit; cout <« "Enter a one-digit number; press return." << endl; cin >> digit; /* TO BE FILLED IN */ /* TO BE FILLED IN */ counter = sum while /* TO BE FILLED IN */ { /* TO BE FILLED IN */ cout << "Sum of digits between 0 and " « digit << " is " << sum << endl; return 0; 3 Event-controlled Loops Use program shell CountUC for exercises 4 and 5. // Program CountUC counts the number of uppercase letters // on a line. tinclude <iostream> using namespace std; int main () { char letter; int letterCt; /* TO BE FILLED IN */ return 0; } Exercise 4. Fill in the body of program CountUC so that the number of uppercase letters on a line of input is printed. Run your program with the following input and show the result. (Hint: 1. Remember that the ASCII code of letters are in alphabetic order, so an uppercase letter must satisfy letter>='A' && letter<='Z'. 2. You can use cin.get(letter) to get each character in the line and exit the loop when it's '\n'.) Input AbbaDabbaD00 Output Exercise 5. Change program CountUC from Exercise 4 so that the counting stops if the input line contains a digit. Run your program with the following data and show the results. Output Input ABBAIDABBA2D00
