C++ String cbegin
It provides a reference to the initial element within the string.
Difference b/w cbegin and begin
The sole contrast between cbegin and begin lies in the fact that cbegin provides a constant iterator indicating the constant value.
Syntax
Consider a string str. Its syntax would be:
Example
str.cbegin();
Parameter
This function does not contain any parameter.
Return value
This function provides the pointer to the initial element of the string.
Example 1
Let's see a simple example:
Example
#include<iostream>
#include<string>
using namespace std;
int main()
{
string str = "java tutorial";
for(int i =str.cbegin();i!=str.end();i++)
cout<<str[i];
return 0;
}
In this instance, the string 'java tutorial' is showcased utilizing the cbegin method.
Output:
Output
java tutorial
Example 2
Let's see another simple example:
Example
#include<iostream>
#include<vector>
#include<iterator>
using namespace std;
int main()
{
vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(4);
v.push_back(5);
for(auto i =v.cbegin();i!=v.end();++i)
cout<<*i;
return 0;
}
Output:
In this instance, an array holding integer values is showcased utilizing cbegin.
