私はコードをコンパイルしようとすると、私は次の警告を得る:GCCコンパイラの警告:フォーマット「%cが」「のchar *」型の引数を期待していますが、引数2は型を持つ「int型*」[-Wformat]
をexercise6.c:32:14:警告:フォーマット '%c'は 'char *'型の引数を要求しますが、引数2は 'int *'型を持ちます[-Wformat]
この警告の原因とは何ですか私が直します?
/*Write a program that displays the contents of a file at the terminal 20 lines at
a time. At the end of each 20 lines, have the program wait for a character to be
entered from the terminal. If the character is the letter q, the program should
stop the display of the file; any other character should cause the next 20 lines
from the file to be displayed.*/
