Answer:
The program written in Python is as follows:
file_handler = open("numbers.dat","r")
nums = 0
for line in file_handler:
try:
nums+=int(line)
except ValueError:
continue
file_handler.close()
print("Sum: "+str(nums))
Explanation:
The file handler is used to enable the program reads content of the file numbers.dat
file_handler = open("numbers.dat","r")
This initializes the sum of numbers to 0
nums = 0
This iterates through the line of the file
for line in file_handler:
The try exception is used to prevent program crash if data other than integer is read
try:
This adds numbers on each line
nums+=int(line)
This exception is returned for data other than integers
except ValueError:
continue
This closes the file handler
file_handler.close()
This prints the calculated sum
print("Sum: "+str(nums))
