Explanation & Hints:

The output of the provided C program will be 2. Here’s a step-by-step explanation:

  1. int var; declares an integer variable named var.
  2. var = 1; sets the value of var to 1.
  3. var = 2; then changes the value of var to 2.
  4. /* var = 3; */ is commented out and thus has no effect on the program’s execution.
  5. print("%d", var); should be printf("%d", var); to correctly compile in C. Assuming this is a typo and should be printf, it will print the current value of var, which is 2.

Therefore, the correct output, assuming the typo is corrected to printf, is 2.
