代码如下:

#include <stdio.h>
#include <string.h>
#define SIZE 20
int main(){    
    char str[SIZE]={&#39;\0&#39;};   
    int count=0;
    printf("plz input the string\n");
    gets(str);
    puts(str);   
    int length = strlen(str);  
    for (int i=0;i<length;i++){
        if(str[i]!=&#39; &#39;){         
            count++;       
            while(str[i]!=&#39; &#39;&&str[i]!=&#39;\0&#39;){
                i++;
            }
        }
    }
    printf("%d\n",count); 
    return 0;
}

程序解释:

‘\0’和‘0’的区别: 在c语言中,它们都是字符,都用对应的ASCII码来存储。例如第一个ASCII码,0,对应字符为(Null),就是 ‘\0’,即空字符。我们在c语言中判断一个字符串是否结束的标志就是看是否遇到‘\0’,如果遇到‘\0’,则表示字符串结束。字符‘0’和数字0的区别:前者是字符常量,后者是整形常量,但是字符常量可以像整数一样在程序中参与相关运算。
