Question

5. Write the complete program to sum all numbers between 56 and 79. For full credits write the: a) Algorithm (5 points) b) Pseudocode (5 points) c) Flowchart (5 points) d) Test cases (5 points) e) Source code that is put in the Python complier (5 points)

Answer 1

5. a) Algorithm:

1. Start
2. Declare variables named i and sum as integers
3. Initialize i to 56 and sum to 0
4. Loop until i reaches 79
   1. Add i to the sum
   2. Increment i by 1
5. End Loop
6. Stop

5. b) Pseudocode:

Sum_56_To_79()

// To sum numbers between 56 and 79

{

i:= 0;

sum:=0;

for i:= 56 to 79 do

sum := sum + i ;

write(sum);

}

5. c) Flowchart:

null

5. d) Test Cases:

There will be only one test case and the output is: 1620

5. e) Source Code(Python compiler):

# variable to store sum
sum = 0
#loop to sum the numbers using range() from 56 to 79 i.e., (80-1)
for i in range(56,80):
    sum = sum + i

#printing the result
print("Sum of number between 56 and 79: ",sum)

Sample Output:
