How to get Item in a Vector at a Specific Index in C++ ?

Answer

To access an item in a C++ vector at a specific index, you can use the indexing operator ([]).

✐ Examples

1 Access Item at Specific Index - Integer Vector

In this example,

We create a vector of integers named intVector.
We access an item at a specific index in the integer vector using the indexing operator [] and specify the index of the item we want to access.
The integer item at the specified index is returned.
We print the accessed integer item to the console.

C++ Program

#include <iostream>
#include <vector>

int main() {
    // Create a vector of integers
    std::vector<int> intVector = {10, 20, 30, 40};

    // Access item at index 2
    int accessedIntItem = intVector[2];

    // Print accessed integer item
    std::cout << "Accessed integer item: " << accessedIntItem << std::endl;
    return 0;
}

Output

Accessed integer item: 30

2 Access Item at Specific Index - String Vector

In this example,

We create a vector of strings named strVector.
We access an item at a specific index in the string vector using the indexing operator [] and specify the index of the item we want to access.
The string item at the specified index is returned.
We print the accessed string item to the console.

C++ Program

#include <iostream>
#include <vector>
#include <string>

int main() {
    // Create a vector of strings
    std::vector<std::string> strVector = {"apple", "banana", "cherry", "date"};

    // Access item at index 2
    std::string accessedStrItem = strVector[2];

    // Print accessed string item
    std::cout << "Accessed string item: " << accessedStrItem << std::endl;
    return 0;
}

Output

Accessed string item: cherry
