#include

int count_letter(char *str)

{

char *p = str;

int cnt = 0;

//开始计数

while (*p != '\0') {

if ((*p >= 'a' & *p = 'A' & *p cnt++;

}

p++;

}

//计数完成

printf(＂letter cnt:%d\n＂, cnt)； //打印出英文字母总数

return cnt； //计数结果返回

}

int main()

{

char *str = ＂gkdial9-1.;J19D-=-=YdlUImf＂； //实例字符串

count_letter(str)； //调用计数函数

return 0;

}

以上源码。

主要思路为循环到字符串结尾，逐字符判断是否属于字母范围（A到Z或a到z），如果为字母则计数器+1，直到字符为结束符'\0'为止，表示字符串结束，并将结果返回给函数调用者。
