c++字符串连接

string name="nihao";string spa=""; string str;//str = "常量字符串"+"kowin";//常量字符串不能直接相加,报错str = "常量字符串" + name + "kowin";//可在两常量字符串中间或开头加变量字符串即可cout<<str<<endl;str = spa + "常量字符串"+"kowin";//故可取巧，加一个空字符串变量spa到开头，就可以达到想要的效果cout<<str<<endl;string str1 = "字符串";int n = 10;char num[10];str1= str1 + itoa(n,num,10);//字符串与整型连接，先用itoa把整型转换，再连接cout<<str1<<endl;
