I solved a problem some day ago. In that problem you had to format an integer. I found it hard to solve. So here I am sharing my problem with you.
Problem:
Read an integer variable and print it in which the digits are separated into groups of three by commas.
Input: 12345678
Output: 12,345,678
Any changes of my code will be appreciated.
def format(text, l, formatted):
"""format the text if it is devided by 3 """
if l <= 3:
formatted += text
elif l%3 == 0 and l/3 != 1:
comma = l / 3 - 1
comma_counter = 0
pos = 0
while pos < len(text) and text[pos] != None:
if pos != 0 and (pos+1)%3 == 0:
formatted += text[pos]
comma_counter += 1
if comma_counter <= comma:
formatted += ','
else:
formatted += text[pos]
pos += 1
return formatted
n = input()
if n in '-':
formatted = '-'
text = n.replace('-', '')
l = len(text)
if l <= 3:
formatted += text
print(formatted)
elif l%3 == 0:
print(format(text, l, formatted))
else:
fc = l%3
if fc == 1:
formatted += text[0] + ','
text = text[1:]
l = len(text)
print(format(text, l, formatted))
else:
formatted += text[:2] + ','
text = text[2:]
l = len(text)
print(format(text, l, formatted))
else:
formatted = ''
text = n
l = len(text)
if l <= 3:
formatted += text
print(formatted)
elif l%3 == 0:
print(format(text, l, formatted))
else:
fc = l%3
if fc == 1:
formatted += text[0] + ','
text = text[1:]
l = len(text)
print(format(text, l, formatted))
else:
formatted += text[:2] + ','
text = text[2:]
l = len(text)
print(format(text, l, formatted))
Hy guys, how can I read comma delimited list from text file into an array in c++
