このプログラムの最後の部分で苦労しています。配列を 2 つの異なる関数に渡す必要がありますが、その方法がわかりません。
私が発生する唯一のエラー:ここ:
input(array[20]);
calculate(array[20],&pairs);
そしてここ:
//exit,
exit;
それ以外は、必要な方法で動作するはずですが、通常の変数でポインターを使用する方法を理解しましたが、配列の動作が異なり、何をすべきかわかりません...
ドキュメントは半分完成しており、説明で概説されているループを最後に追加する必要がありますが、配列を渡すのに助けが必要です。
また、私の終了行に関連するエラーは質問とは無関係ですが、修正を知っていれば素晴らしいでしょう!
/*
Description: Do not use global variables. Pass your arguments by value and
by reference. Using arrays and modular programming techniques,
write a C program that will allow a user to populate an array
with integers, and then compute and print out the number of
adjacent pairs in the array (i.e. the number of occurrences where
an array element is the same as its neighbors). For example, if
the array contained [2,3,3,4,52,52,4,4,4,4,7,7,1], the number of
adjacent pairs is 6. The program should give the user the option
of examining more than one array (i.e. loop). Assume the array has
a max. of 20 elements. The main() function should primarily be
responsible to direct the flow of logic. That is: use one
function to obtain input (pass by reference), another function to
do processing (pass by value), and perhaps a third function to do
output (pass by value). The main() function should call the input
function and the processing function.
