C Program to Demonstrate the increment and decrement operators

Posted on by Sandeepa Nadahalli

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

The Program

/* C Program to demonstrate increment and decrement operators */
main()
{
/*
* ++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.
*/
int i=1,j=1;
puts("\tDemo 1");
printf("\t%d %d\n",++i, j++); /* O/P 2 1 */
printf("\t%d %d\n",i, j); /* O/P 2 2 */
i=1; j=1;
puts("\n\tDemo 2");
printf("\t%d \n", i=j++); /* O/P 1 */
printf("\t%d \n", i=++j); /* O/P 3 */
i = 0; j = 0;
puts("\n\tDemo 3");
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 */
}

C Program to find GCD and LCM using Recursion

Posted on by Sandeepa Nadahalli
C Program to find the GCD and LCM. In this program we used the Recursion method. Recursion is the programming technique that a process invoking itself again and again. Here find_gcd() and find_(lcm) are the recursive methods. for example LCM and GCD of 8,12 is 24 and 4 Read more about C Programming Language .

C Program to calculate factorial using Recursive function

Posted on by Sandeepa Nadahalli
C Program to find the factorial of a number. In this program we used the Recursion method. Recursion is the programming technique that a process invoking itself again and again. The standard recursive function for factorial is factorial=n*fact(n-1). factorial of number denoted by ‘!’, means product of all non negative integers from 1 to number. example: 5!=5*4*3*2*1=120.

C Program to Demonstrate #if, #else & #endif preprocessors.

Posted on by Sandeepa Nadahalli
C Program to demonstrate the Preprocessor directives like #if, #else, #define, #endif. C Preprocessors are not the program statements, they are executed before the actual compilation of the code. C Preprocessors substitute the code where they called, i.e they replace the code as they defined. #if, #else are the conditional directives. Here at the compile time #if value is false, so #else part is execute.

C Program to find the Character types. Here we used the isdidit(), isalpa(), and isspace() functions.isdigit() function returns true if argument is a decimal digit, otherwise false. isalpa() function returns true if argument is a defined set of characters in c, otherwise false. isspace() function returns true if argument is a white space character (one of ‘ ‘ ‘f’ ‘n’ ‘r’ ‘t’ ‘v’), otherwise false.
