if else Statement in C++ language
The if statement lets you do something if a condition is true. If it isn’t true, nothing happens. But suppose we want to do one thing if a condition is true, and do something else if it’s false.
That’s where the if...else statement comes in. It consists of an if statement, followed by a statement or block of statements, followed by the keyword else, followed by another statement or block of statements.
Syntax of if....else Statement:
if(condition)
{
// Statements inside body of if
}
else if(condition)
{
//Statements inside body of else if
}
else
{
//Statements inside body of else
}

#include using namespace std;
int main()
{
int x;
cout > x;
if( x > 100 )
cout << “That number is greater than 100
”;
else
cout << “That number is not greater than 100
”;
return 0;
}
Output:
Enter a number: 300 That number is greater than 100 Enter a number: 3 That number is not greater than 100
