C / C ++How to强制转换malloc() in C++ without needing it in C?

The increment operator is used to increase the value by one, and decrement is the opposite of increment. The decrement operator decreases the value by one.

pre-incrementing (++ i) -Incrementing the value before assigning it to a variable1.

incrementing after (i ++) -After assigning a value to a variable, the value will increment.

The following is the syntax for incrementing before and after.

++variable_name;　//　Pre-increment
variable_name++;　//　Post-increment

Here,

variable_name-any name given by the user to a variable.

This is C ++incrementing before and after.

Example

#include <iostream>
using namespace std;
int main() {
　　　int i =　5;
　　　cout << "The pre-incremented value: " << i;
　　　while(++i <　10　)
　　　cout << "\t" << i;
　　　cout << "\nThe post-incremented value: " << i;
　　　while(i++　<　15　)
　　　cout << "\t" << i;
　　　return 0;
}

Output Result

The pre-incremented value:　5　6　789
The post-incremented value:　10　1112131415
