【程序17】
题目:输入一行字符,分别统计出其中英文字母、空格、数字和其它字符的个数。
1.程序分析:利用while语句,条件为输入的字符不为'\n'.
2.程序源代码:
'''
import string
s = input('input a string:\n')
letters = 0
space = 0
digit = 0
others = 0
for c in s:
if c.isalpha():
letters += 1
elif c.isspace():
space += 1
elif c.isdigit():
digit += 1
else:
others += 1
print ('char = %d,space = %d,digit = %d,others = %d' % (letters,space,digit,others))
C:
void py17()
{
char c;
char letters=0;
int space=0;
int digit=0;
int others=0;
printf("please input string:\n");
while((c=getchar())!='\n')
{
if(c>='a'&&c<='z'||c>='A'&&c<='Z')
letters++;
else if(c==' ')
space++;
else if(c>='0'&&c<='9')
digit++;
else
others++;
}
printf("all in all:char=%d space=%d digit=%d others=%d\n",letters,
space,digit,others);
}
