IndexOf in c++

Question

Hello guys , i already learn c# , and now i am learning c++ so i can see that they are very similiary....

But i have a problem ...

I want to know what is the number of the char “x” in a string .

For example

C#

String a = “hello”;
Consolé.WriteLine( a.IndexOf(“h”) );

Output :
0...

So .. how can i do the same but in c++?

jayKrishna thank you

this is the code

str.find_first_of('a');

#include<iostream>
using namespace std;
int main()
{
string str = "javatpoint tutorial";
cout << "String contains :" << str<< '\n';
cout <<"Position of the first occurrence of 'a' character is :" << str.find_first_of('a');
return 0;

please check the pagine

}

Answer 2

In c++, s[i] return char at index i.
Use a loop and compare with s[i] =='h'

And also check string function in c++. There are function to check char is in string or not.. .
