The if statement & The switch statement

An if statement has the following form:

if (condition)
  {
  // code to execute if condition is true
  }
  else 
  {
  // code to execute if condition is false
}

Here is an example:

#include <iostream.h>

int main() {
int a = 5;
int b = 7;
  
  if (a> b) {
  cout << "a is greater than b" << endl;
  }
  else {
  cout << "a is less than b" << endl;
  }
  
  return 0;
}

An switch statement allows you to compound a group of if statements. An switch statement has the following syntax:

switch(integer_val){
  case val_1:
  // code to execute if integer_val is val_1
  break;
  ...
  case val_n:
  // code to execute if integer_val is val_n
  break;
  default:
  // code to execute if integer_val is none of the above
}

switch (color) {
	case 1:
		cout << "red" << endl;
		break;
	case 2:
		cout << "blue" << endl;
		break;
	default:
		cout << "white" << endl;
}
