How to get First N Characters in String in C++ ?

Answer

In C++, you can use string slicing or the `substr` method to get the first N characters from a string.

✐ Examples

1 First 5 Characters of "Hello World" String

In this example,

We create a string named str with a value of "Hello World".
We use string slicing with str.substr(0, 5) to get the first 5 characters.
Finally, we print the first 5 characters.

C++ Program

#include <iostream>
#include <string>

int main() {
    std::string str = "Hello World";
    std::string first5Chars = str.substr(0, 5);
    std::cout << "First 5 characters of the string are: " << first5Chars << std::endl;
    return 0;
}

Output

First 5 characters of the string are: Hello

2 First 3 Characters of "apple" String

In this example,

We create a string named str with a value of "apple".
We use string slicing with str.substr(0, 3) to get the first 3 characters.
Finally, we print the first 3 characters.

C++ Program

#include <iostream>
#include <string>

int main() {
    std::string str = "apple";
    std::string first3Chars = str.substr(0, 3);
    std::cout << "First 3 characters of the string are: " << first3Chars << std::endl;
    return 0;
}

Output

First 3 characters of the string are: app
