Conditions and If Statements in C++

 

 Conditions and If Statements in C++

C++ has the following conditional statements:

• Use if to specify a block of code to be executed, if a specified condition is true
• Use else to specify a block of code to be executed, if the same condition is false
• Use else if to specify a new condition to test, if the first condition is false
• Use switch to specify many alternative blocks of code to be executed

The if Statement

Use the if statement to specify a block of C++ code to be executed if a condition is true.

if (condition) {
  // block of code to be executed if the condition is true
}

EG:

int x = 20;
int y = 18;
if (x > y)

 {
  cout << "x is greater than y";
 }

• Less than: a < b
• Less than or equal to: a <= b
• Greater than: a > b
• Greater than or equal to: a >= b
• Equal to a == b
• Not Equal to: a != b

You can use these conditions to perform different actions for different decisions.
