1.Integer - Stores integer(whole number)
Example: int myNum = 5;
2.Float - Stores floating number with decimal number.
Example: 99.0
3.Char - Stores single character within the single quotes.
Example: 'a','g'.
4.Boolean - Stores boolean values.
Example:True,False
5.String - Stores texts with the double quotes.

Integer:
program:
#include <iostream>
int main() {
int user_input;
std::cout << "Enter a number: ";
std::cin >> user_input;
std::cout << "You entered: " << user_input << std::endl;
return 0;
}
Output:
Enter a number: [user enters a number, e.g. 42]
You entered: 42
Float:
Program:
#include <iostream>
int main() {
float user_input;
std::cout << "Enter a number: ";
std::cin >> user_input;
std::cout << "You entered: " << user_input << std::endl;
return 0;
}
Output:
Enter a number: 3.14159
You entered: 3.14159
Char:
Program:
#include <iostream>
int main() {
char user_input;
std::cout << "Enter a character: ";
std::cin >> user_input;
std::cout << "You entered: " << user_input << std::endl;
return 0;
}
Output:
Enter a character: G
You entered: G
Boolean:
Program:
#include <iostream>
int main() {
bool is_valid = true;
std::cout << "Is the input valid? " << is_valid << std::endl;
return 0;
}
Output:
Is the input valid? 10
String:
Program:
#include <iostream>
#include <string>
int main() {
std::string user_input;
std::cout << "Enter a string: ";
std::getline(std::cin, user_input);
std::cout << "You entered: " << user_input << std::endl;
return 0;
}
Output:
Enter a string: Gocourse
