C語言 輸入字串，程式設計統計其中的字母 數字 空格 含製表符 標點符號的個數並輸出
include include int main int argc,char argv printf 該字串的字母個數 d個，數字個數 d個，空格個數 d個，標點個數 d個 n alpha,digit,space,spunct return 0 include include int main in...
輸入若干字串,按字串長度由小到大重新排序輸出 使用指標陣列處理
輸入五個字串，然後按字串長度從小到大排序，先把源程式複製一下，char string 5 定義了指標陣列。include include include int main for i 0 i 5 i printf nbefore sort n for i 0 i 5 i for i 0 i 5 i ...
C字串中刪除輸入的字母，如何在c 的字串中刪除某個字串
include include void main void delete string char str,char ch str j 0 這個地方也錯了，j 0，相當於把首字元用空格覆蓋 錯了delete string str 這裡是兩個引數 陣列，被刪除的字母 delete string str...
