[编程入门]自定义函数之字符类型统计-题解（C语言代码）

参考代码:

#include<stdio.h>
#include<string.h>
void CharacterTypeStatistics(char *string,int *letter,int *number,int *space,int *anothersize)
{
    int len=0;
    int i=0;
    len=strlen(string);
    *letter=0,*number=0,*space=0,*anothersize=0;
    for(i=0;i<len;i++)
    {
        if(string[i]==' ')
        *space+=1;
        else if(string[i]<='9'&&string[i]>='0')
        *number+=1;
        else if((string[i]<='z'&&string[i]>='a')||(string[i]<='Z'&&string[i]>='A'))
        *letter+=1;
        else
        *anothersize+=1;
    }
}
int main()
{
    char string[1024];
    scanf("%[^\n]",string);
    int letter=0,number=0,space=0,anothersize=0;
    CharacterTypeStatistics(string,&letter,&number,&space,&anothersize);
    printf("%d %d %d %d\n",letter,number,space,anothersize);
    return 0;
}
