[英]Need help creating a function and error with switch statement
我正在使用switch語句來處理一些代碼,這些代碼將在main中創建一個要調用的函數。 我在switch語句中遇到開關數量問題。 另外,如何為這10種情況創建函數? 非常困惑,任何幫助不勝感激! 謝謝! 這是我當前的代碼:
#include <iostream>
using namespace std;
void constitution(); // the function that will call my amendments in my main function
// how will i create this will 10 possible amendments to choose from?
// There are 4 pirates and they will vote either yes or no,
int main()
{
cout << "Below is a list of the 10 amendments that the two pirates will vote on according to the ships constitution" << endl;
string amendments = 0;
cin >> amendments; // selecting the amendment
switch (amendments)
{
// for outputting the amendment(s) voted on, which will
// be passed on to a function in main to call
case 1: cout << "What does the fox say? Whatever WE tell it to"; //case 1-10 are the 10 amendments to be voted on
break;
case 2: cout << "From now on the annual Cinco de Mayo party will be held on March 8th ";
break;
case 3: cout << "Beginning this year, sharks shall have a week dedicated to us";
break;
case 4: cout << "Pirates are now allowed to talk about fight club";
break;
case 5: cout << "When in Rome, the Romans will do as WE do.";
break;
case 6: cout << "Our mothers will immediately get tattoos that say SON";
break;
case 7: cout << "From now on the President will take our birthdays off.";
break;
case 8: cout << "If we say something costs an arm and a leg, it does";
break;
case 9: cout << "Freemasons are ordered to learn OUR secret handshake.";
break;
case 10: cout << "If a tree falls in the forest and no one is around, it will make a sound only with our permission ";
break;
default: cout << "This won't be used since a amendment will always be voted on, thus never be shown or checked I believe.. (Please correct me) ";
break;
}
return 0;
}
您唯一需要更改的就是將修正設為整數,因為switch期望為int。
int main()
{
cout << "Below is a list of the 10 amendments that the two pirates will vote on according to the ships constitution" << endl;
int amendments = 0;
cin >> amendments; // selecting the amendment
switch (amendments)
{
...
}
如果您想使用修正作為字符串,恐怕您將無法通過switch進行檢查。 相反,您應該使用if / else if語句:
if(amendments == '1') {
...
} else if (amendments == '2') {
...
}
