C++ insert character
To insert a character in C++, you can use the insert()
function from the string
class. Here are the steps to do so:
Declare a string variable: Start by declaring a string variable and assigning it a value. For example, you can declare a string variable called
myString
and assign it the value "Hello World".Include the necessary header file: To use the
string
class, you need to include the<string>
header file at the beginning of your C++ program.Use the
insert()
function: To insert a character at a specific position in the string, call theinsert()
function on the string variable. Theinsert()
function takes three arguments: the position at which the character should be inserted, the character to be inserted, and the number of times the character should be inserted.Print the modified string: After inserting the character, you can print the modified string to verify the changes. You can use the
cout
statement to display the string on the console.
Here's an example code snippet that demonstrates the insertion of a character in C++:
#include <iostream>
#include <string>
int main() {
std::string myString = "Hello World";
myString.insert(5, "!"); // Inserting '!' at position 5
std::cout << myString << std::endl; // Output: Hello! World
return 0;
}
In this example, the character '!' is inserted at position 5 in the string "Hello World". The output will be "Hello! World" when the modified string is printed.
