我目前正在研究字符串,并且正在研究这个简单的示例。我试图在 logSuccess 字符串中传递“生日” 用户输入。做了很多谷歌搜索,但还没有找到解决方案。有提示吗?
#include <iostream>
#include <string>
#include <stdlib.h>
using namespace std;
std::string birthdate;
void printString(const std::string& string)
{
std::cout << string << std::endl;
}
void getBirthdate()
{
std::cout<<"When is your birthday? "<<std::endl;
cin>>birthdate;
}
int main()
{
std::string name = std::string("Dame") + " hello!";
std::string logSuccess = std::string("Thank you! We will send you a postcard on ") + birthdate;
printString(name);
getBirthdate();
printString(logSuccess);
std::cin.get();
}

在创建消息并将其分配给logSuccess变量时,birthdate变量为空。从用户获得输入后,您想用数据填充logSuccess。

您的错误在这里:
OK|master
应该是:
a = ['master', 'FAULT', None]
b = ['FAULT', None, 'master']
c = [None, 'master', 'FAULT']
def getMsg(state):
d = []
for i in state:
if i == 'master':
d.append('OK')
else:
d.append('CRITICAL')
return(d)
print(getMsg(a)) # --> ['OK', 'CRITICAL', 'CRITICAL']
print(getMsg(b)) # --> ['CRITICAL', 'CRITICAL', 'OK']
print(getMsg(c)) # --> ['CRITICAL', 'OK', 'CRITICAL']
