Netbeans ツールを構成したところ、(最終的に) 動作しました :) (Hello World で確認しました)。私たちはシフトしていたので、3か月ほどのギャップがあったので、回文チェッカーやブレブレブレなどの他のプログラムではなく、計算機を作成したいと思いました。コードは次のとおりです。
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
void addition(int,int);
void subtraction(int,int);
void mutiplication(int,int);
void division(int,int);
int main() {
int x,y,choice,redo = 1;
while(redo)
{
printf("\nWelcome to the CalC :D\nPlease make a choice\n1.Addition\n2.Subtraction\n3.Multiplication\n4.Division\n>");
scanf("%d",&choice);
switch(choice);
{
case '1' :
{
printf("Enter the first number\n>");
scanf("%d",&x);
printf("\nThe second number?\n>");
scanf("%d",&y);
addition(x,y);
}
case '2' :
{
printf("Enter the first number\n>");
scanf("%d",&x);
printf("\nThe number to be subtracted from %d is?\n>",x);
scanf("%d",&y);
subtraction(x,y);
}
case '3' :
{
printf("Enter the first number\n>");
scanf("%d",&x);
printf("\nThe number to be multiplied with %d is?\n>",x);
scanf("%d",&y);
multiplication(x,y);
}
case '4' :
{
printf("Enter the first number\n>");
scanf("%d",&x);
printf("\nThe number to be divided by %d is?\n>",x);
scanf("%d",&y);
division(x,y);
}
}
printf("\nWould you like to make another calculation?\n1.Yes '_' \n2.No! :p\n>");
scanf("%d",&redo);
}
return (EXIT_SUCCESS);
}
void addition(int x,int y)
{
int sum;
sum = x + y;
printf("\nThe sum of %d and %d is %d\n(Press enter to display the menu)",x,y,sum);
getch();
}
void subtraction(int x,int y)
{
int difference;
ce;
difference = x - y;
printf("The difference between %d and %d is %d\n(Press enter to display the menu)",x,y,difference);
getch();
}
void multiplication(int x,int y)
{
int product;
product = x * y;
printf("The product of %d and %d is %d\n(Press enter to display the menu)",x,y,product);
getch();
}
void division(int x,int y)
{
float quotent;
quotent = (float)x/(float)y;
printf("The quotient of %d and %d is %.2f\n(Press enter to display the menu)",x,y,quotent);
getch();
}
そして、これは私が得るエラーです:

私は ::blocks のコーディングに慣れているので、ここで何が問題なのかよくわかりません :\ 助けてください、スイッチ ラベルを '1'、'2'、'3'、'4' として明確に定義しました! みんなありがとう ：）
