我刚刚配置了我的 Netbeans 工具，并且（最终）它工作了:)（我检查了 Hello World）。我们正在转变，所以我有 3 个月的差距，所以我想我会做一个计算器，而不是像回文检查器和 bleh bleh bleh 之类的其他程序。所以这里是代码：
#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();
}
这是我得到的错误：

我习惯了编码::blocks所以我真的不知道这里有什么问题:\请帮帮我，我明确地将开关标签定义为'1'，'2'，'3'，'4'！多谢你们 ：）
