Strings
A string is a sequence of characters representing text. Strings are typically enclosed in quotation marks and can be stored in variables for later use in a program.
C++
#include <iostream> #include <string> int main() { // Declare a string variable std::string str = "codinghome"; }Integers and Floating Point Numbers
Simply said, Integers are used for numbers without a decimal, and Float is used for numbers with decimals, simply said. There is more to that but we are keeping it simple.
C++
#include <iostream> int main() { // Declare an integer variable int num = 10; // Declare a floating-point variable float fnum = 10.5; }Printing an output to the terminal/console:
C++
#include <iostream> int main() { // Declare an integer variable int num = 10; // Declare a floating-point variable float fnum = 10.5; std::cout << "num: " << num << std::endl; // <-- Prints the integer variable (variable num) std::cout << "fnum: " << fnum << std::endl; // <-- Prints the floating point variable (variable fnum) return 0; }Other Data Types
As previously listed:
string - Integers (whole number) (2 or 4 bytes).int - floating point number (4 bytes).float - Stores strings (Text) (use ').But there are other data types in C++, such as:
double - Stores strings (Text) (use ").char - floating point number (8 bytes).bool - true (1) or false (0) (1 byte).
