In this C++ tutorial, you shall learn how to iterate over the character of a given string using For loop, with example programs.

C++ Iterate over Characters of a String

To iterate over the characters of a string in C++, we can use foreach loop statement.

The following code snippet shows how to iterate over the characters of a string str using foreach loop.

for (ch& : str) {
    //code
}

Example

In the following program, we take a string in str variable, and iterate over the characters of the string using for loop.

main.cpp

#include <iostream>
using namespace std;

int main() {
    string str = "apple";
    for(char& ch : str) {
      cout << ch << endl;
   }
}

Output

a
p
p
l
