C program which demonstrates the working of increment(++) and decrement(–) operators. Increment operator ++ adds 1 to its operand and Decrement operator — subtracts 1 from its operand.
These operators may be used either as a prefix operator or post-fix operator. Read more here: Increment and decrement operators
|/* C Program to demonstrate increment and decrement operators */|
|* ++i -> i incremented before i is used.|
|* --i -> i decremented before i is used.|
|* j++ -> j is incremented AFTER j has been used.|
|* j-- -> j is decremented AFTER j has been used.|
|printf("\t%d %d\n",++i, j++); /* O/P 2 1 */|
|printf("\t%d %d\n",i, j); /* O/P 2 2 */|
|printf("\t%d \n", i=j++); /* O/P 1 */|
|printf("\t%d \n", i=++j); /* O/P 3 */|
|i = 0; j = 0;|
|if ( (i++ == 1) && (j++ == 1)) puts("Some text");|
|/* Will i and j get incremented? The answer is NO! Because|
|* the expression in the left of '&&' resolves to false the|
|* compiler does NOT execute the expression on the right and|
|* so 'j' does not get executed!!!!! */|
|printf("\t%d %d\n",i, j); /* O/P 1 0 */|
