Question

The program requests the user to enter a sequence of numbers and displays the accumulation sum per entry. (set the MAX_ENTRY =5, and initialize the total to zero before starting)

Result:
This program calculates the sum of 5 numbers as you enter them
Enter number 0:3
0+3=3
Enter number 1:4
3+4=7
Enter number 2: 5
7+5=12
Enter number 3:3
12+3=15
Enter number 4:5
15+5=20
Done

Answer 1

The program prompts the user to enter numbers up to a specified maximum (5 in this case), adds them to an accumulated sum, and displays the sum after each entry, demonstrating basic algorithmic thinking and addition rules.

Step-by-step explanation:

Understanding Accumulation Sum

The program described in the question continually adds numbers to a running total or accumulation sum, demonstrating a simple form of algorithmic thinking. Starting with an initial total value of zero, the program requests input for a limited number of times, defined as MAX_ENTRY which is set to be 5 in this case.

The behavior of the program can be summarized as follows:

1. The user is prompted to enter a number.
2. The number entered by the user is added to the total.
3. The updated total is displayed.
4. Steps 1-3 are repeated until 5 numbers have been entered (MAX_ENTRY).

For example, if the user enters '3' as the first number, the program adds this to the initial total (0), resulting in a new total of '3'. This process is repeated for each of the subsequent entries.

The rules of addition (commutative property) apply here as well. When combining positive numbers, the sum carries a positive or '+ve' sign. When combining negative numbers, the sum carries a negative or '-ve' sign. And when numbers with opposite signs are added, one must subtract the smaller number from the larger one, with the sum carrying the sign of the larger number. Subtraction can be treated as the addition of a negative number.
