17. Another function example

• Earlier we looked at code to find the larger of two values. Here is a function that compares the two values and returns the larger value:

  
      int max( int a, int b )  // this function takes 2 parameters
      {
          if ( a < b ) {
              return b;
          } else {
              return a;
          }
      }
  
  

• Usage example:

  
      int x = max( 7, 9 );      // x becomes 9
      int y = max( 19, -27 );   // y becomes 19
      int z = max( 20, 20 );    // z becomes 20
