编程入门]自定义函数之字符类型统计

解题思路:

注意事项:

参考代码:

#include<stdio.h>

void Statistic(char* str,int n)

{

int i;

int character = 0;

int number = 0;

int space = 0;

int other_character = 0;

for (i = 0; i < n; i++)

{

if ((((*str) >= 65) && ((*str) <= 90)) || (((*str) >= 97) && ((*str) <= 122)))

{

character++;

}

else if(((*str) >= 48) && ((*str) <= 57))

{

number++;

}

else if ((*str) == 32)

{

space++;

}

else

{

other_character++;

}

str++;

}

printf("%d %d %d %d", character, number, space, other_character);

}

int main()

{

char str[100];

gets(str);

Statistic(str, strlen(str));

return 0;

}
