Creating a Basic Mathmatic Program in C++

All programs have the following:

#include <stdio.h>
#include <stdlib.h>

int main()
{

system("pause");
return 0;
}

To declare the identifiers you do the following:

data_type variable_name;

Example:

int a;
float b;
char c;

If you want to make a simple math equation, like adding two numbers, here's an example:

#include <stdio.h>
#include <stdlib.h>

int main()
{
int a, b, c; //declaring the variables

printf("Insert the first number: "); //asking the user to input the number
scanf("%d", &a); //saving that number on the variable "a"

printf("Insert the second number: "); //see above
scanf("%d", &b); //see above

c=a+b; //self-explanatory.

printf("The result is: %d ", c); //the user will get the answer.

system("pause");
return 0;
}
