C++ String operator=()

This function is used to assign a new value to the string, replacing all the current contents.

Syntax

Consider two strings str1 and str2. Syntax would be:

str1.operator=(str2);
str1.operator=(ch);
str1.operator=(const char* s);

Parameter

str2 : str2 is a string object, whose value is to be moved.

ch : ch is a character value, whose value is to be moved.

s : s is a pointer to the null terminated sequence of characters.

Return value

It returns *this.

Example 1

Let's see a simple example.

#include<iostream>
using namespace std;
int main()
{
string str ="C Programs";
string str1="Java Programs";
str.operator=(str1);
cout<<str;
return 0; 
}

Output:

Java Programs

Example 2

Let's see an another simple example.

#include<iostream>
using namespace std;
int main()
{
string str ="Maths is my favorite subject";
char* s ="Science is my favorite subject";
str.operator=(s);
cout<<str;
return 0; 
}

Output:

Science is my favorite subject

Example 3

Let's see this example.

#include<iostream>
using namespace std;
int main()
{
string str ="java";
char ch='C';
str.operator=(ch);
cout<<str;
return 0; 
}

Output:
