Question

C语言报错的问题？

main(){
int a;
printf("input integer number: ");
scanf("%d",&a);
switch (a){
case 1:printf("Monday\n");
case 2:printf("Tuesday\n");
case 3:printf("Wednesday\n");
case 4:printf("Thursday\n");
case 5:printf("Friday\n");
case 6:printf("Saturday\n");
case 7:printf("Sunday\n");
default:printf("error\n");
}
C语言报错 C:\Users\Administrator\Desktop\1.c\122102.c In function `main':
14 C:\Users\Administrator\Desktop\1.c\122102.c syntax error at end of input
是什么原因呢

Answer 1

你的程序错误，是在
cout << “Enter the temperature in Celsius:”;
cout << “Fahrenheit value is:”;中用了中文状态下的双引号。

1. #include <cstdio>
   

2. #include <cstdlib>
   

3. #include <iostream>
   

4. using namespace std;
   

5. int main(int nNumberofArgs, char* pszArgs[])
   

6. {
   

7. // enter the temperature in Celsius
   

8. int celsius;
   

9. cout << "Enter the temperature in Celsius:";
   

10. cin >> celsius;
    

11. // calculate conversion factor for Celsius
    

12. // to Fahrenheit
    

13. int factor;
    

14. factor = 212 - 32;
    

15. // use conversion factor to convert Celsius
    

16. // into Fahrenheit values
    

17. int fahrenheit;
    

18. fahrenheit = factor * celsius/100 + 32;
    

19. // output the results (followed by a NewLine)
    

20. cout << "Fahrenheit value is:";
    

21. cout << fahrenheit << endl;
    

22. // wait until user is ready before terminating program
    

23. // to allow the user to see the program results
    

24. system("PAUSE");
    

25. return 0;
    

26. }
    

以上程序正确，可以运行。

如果还不行，那就是编译器的问题。建议:用vc2008，c-free或vc2010.微软已停止对vc6.0进行更新了。(开始不习惯很正常，成为高手后会喜欢例如vc2010的)。
