strcat(destination, c);
printf("%sn", destination);
return 0;
}
函数名: strchr
功 能: 在一个串中查找给定字符的第一个匹配之处...= strchr(string, c);
if (ptr)
printf("The character %c is at position: %dn", c, ptr-string...(string, c);
if (ptr)
printf("The character %c is at position: %dn", c, ptr-string);
else...,不是字符串函数,
isalpha
原型:extern int isalpha(int c);
用法:#include
功能:判断字符c是否为英文字母
说明:当c为英文字母...("%c: %s letter",c,isalpha(c)?"
