Call by value ( Example )

void swap(int x, int y)

{ 
  int temp;
  temp = x;
  x = y;
  y = temp;
  printf("Swapped values are a = %d and b = %d", x, y);
}

void main()
{
  int a = 7, b = 4;
  swap(a, b);
  printf("Original values are a = %d and b = %d", a, b);
  printf("The values after swap are a = %d and b = %d", a, b);
}

Output:
	Original Values are a = 7 and b = 4
	Swapped values are a = 4 and b = 7
