#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
// Variable Declaration
int a;
// Get Input Value
cout<<"Enter the Number :";
cin>>a;
//If Condition Check
if(a > 10)
{
// Block For Condition Success
cout<<a<<" Is Greater than 10";
}
else
{
// Block For Condition Fail
cout<<a<<" Is Less than/Equal 10";
}
// Wait For Output Screen
getch();
return 0;
}
Sample Output
Output 1:
Enter the Number:20
20 Is Greater than 10
Output 2:
Enter the Number:5
5 Is Less than/Equal 10
How It Works
This C++ program demonstrates if..else Statement. It first reads the required values as input, then uses conditional logic to decide the result, and finally prints the output shown in the Sample Output above.
- Declare the variables that hold the program’s data.
- Read the input values that the program will work with.
- Use conditional statements to handle the different cases.
- Print the final result to the console so you can compare it with the sample output.
Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
