Example 1:
x = 5;
if (x >3) x = x + 2;
//x holds the value 7
Example 2:
y = 3;
if (y==4) y = y + 3;
else y = y - 1;
//y holds the value 2 because the condition in the if statement is not true
Example 3:
a = 2;
b = 3;
c = 0;
if (a+b < 4) c++;
else if (a + b < 6) c = c + 4;
else c = c + 5;
//c holds the value 4. The condition in the if statement is false, but the condition in the else if statement is true.
