 从键盘上输入一个字符串, 计算字符串里有多少个空格、小写字母、大写字母、数字。
 
+```c
+#include <stdio.h>
+
+int main(){
+	char str[100], space, low_letter, upp_letter, number;
+	space = low_letter = upp_letter = number = 0;
+	char *p;
+	gets(str);
+	p = str;
+	while(*p != '\0'){
+		if(*p == ' '){
+			space++;
+		}else if(*p >= 'a' && *p <= 'z'){
+			low_letter++;
+		}else if(*p >= 'A' && *p <= 'Z'){
+			upp_letter++;
+		}else if(*p >= '0' && *p <= '9'){
+			number++;
+		}
+		p++;
+	}
+	printf("空格:%d 小写字母:%d 大写字母:%d 数字%d\n",
+		space, low_letter, upp_letter, number);
+	return 0;
+}
+```
+
 ### 2. 字符串排序
 
+```c
+#include <stdio.h>
+#include <string.h>
+
+int main(){
+	char str[100];
+	char temp;
+	int i, j;
+	
+	gets(str);
+	
+	for(i=0;i<strlen(str)-1;i++){
+		for(j=0;j<strlen(str)-1-i;j++){
+			if(*(str+j) > *(str+j+1)){
+				temp = *(str+j);
+				*(str+j) = *(str+j+1);
+				*(str+j+1) = temp;
+			}
+		}
+	}
+	
+	puts(str);
+	return 0;
+}
