#1、使用while循环输入 1 2 3 4 5 6 8 9 10
'''
count = 0
while count < 10:
count += 1 # count = count + 1

print(' ')
else:
print(count)
count = 0
while count < 10:
count += 1 # count = count + 1

'''
#3、输出 1-100 内的所有奇数
#方法一：
# count = 1
# while count < 101:
# print(count)
# count += 2
#方法二：
# count = 1
# while count < 101:
# if count % 2 == 1:
# print(count)
# count += 1
#5、求1-2+3-4+5 ... 99的所有数的和
# sum = 0
# count = 1
# while count < 100:
# if count % 2 == 0:
# sum = sum - count
# else:
# sum = sum + count
# count += 1
# print(sum)

#input 心中有账号，密码 while
