1.自己编写函数，将两个字符串进行复制
#include<iostream>
using namespace std;
int main(){
char str1[]="I love China!",str2[20];
void Strcpy(char *p1,char *p2);
Strcpy(str2,str1);
cout<<"str1: "<<str1<<endl;
cout<<"str2: "<<str2<<endl;
return 0;
}
void Strcpy(char *p2,char *p1){
int i=0;
for(;*p1!='\0';p1++,p2++){
*p2=*p1;
}
*p2='\0';
}
2.使用函数库重的strcpy函数
#include<iostream>
using namespace std;
int main(){
char str1[]="I love China!",str2[20];
strcpy(str2,str1);
cout<<"str1: "<<str1<<endl;
cout<<"str2: "<<str2<<endl;
return 0;
}
3.定义两个字符串变量，然后直接进行赋值
#include<iostream>
#include<string>
using namespace std;
int main(){
string str1="I love China!",str2;
str2=str1;
cout<<"str1: "<<str1<<endl;
cout<<"str2: "<<str2<<endl;
return 0;
}
