• i j: The value of

  • i is increased by 1, i = 4.
  • 4 Assign value to j, j = 4.

Note:

• i j is different from i j. The latter increments i by 1 and then adds it to j.
• i j is also different from i j. The latter first increments i by 1 and then adds i 1 to j.
• i j can only be used for integer variables.

Sample code:

<code class="cpp">int main() {
