Is string function is possible to use for string datatype in c++?

Question

According to me it is not possible...What about your opinion?

Answer 1

Right, we can't use C-string functions to work with C++ string, because C++ string is not a plain char array like C-string.

Easy way to compare two string in C++ is to use comparison operator e.g.

s1 == s2 // are they equal?
s1 != s2 // are they different?

Or use the `compare` method (works like strcmp) 👇

There are various ways to copy a string in C++, some of common ways I happen to have seen:

string s1 = s2
string s1(s2)

Answer 2

Your question is not clear. Explain.

Answer 3

(strcmp(s1,s2) == 0) is the right way.

Answer 4

That is correct for char array ,,,,but not for string datatype

Answer 5

Ipang

Yes that r methods to do operations in string data type...

Like using ==,,,,!=,,,s1=s2 for copy

Answer 6

My question is that if we have two string s1,s2 both are string data type

Now if we do like strcpy(s1,s2);

strcmp(s1,s2);

In c++ ?

Answer 7

No it shows error because

Answer 8

#include<iostream>
#include<cstring>
using namespace std;
main()
{
string s1,s2;
s2="hello";
cout<<s1<<endl;
cout<<s2<<endl;
cout<<"-------------------------------------------------------"<<endl;
strcpy(s1,s2);
cout<<s1<<endl;
cout<<s2<<endl;
}

Answer 9

check the code and tell what is the output?

Answer 10

My bad, You're right.
