C Relational Operators

Relational operators in C programming language are as follows: <, <=, >, >=, ==, != . They are used in Boolean conditions or expression and returns true or false. Here is a program which demonstrate relational operators:

01.#include <stdio.h>

02./* a program demonstrates C relational operators */

03. 

04. 

05.void print_bool(bool value){

06.value == true ? printf("true\n") : printf("false\n");

07.};

08. 

09.void main(){

10.int x = 10, y = 20;

11. 

12.printf("x = %d\n",x);

13.printf("y = %d\n",y);

14. 

15./* demonstrate == operator */

16.bool result = (x == y);

17.printf("bool result = (x == y);");

18.print_bool(result);

19. 

20./* demonstrate != operator */

21.result = (x != y);

22.printf("bool result = (x != y);");

23.print_bool(result);

24. 

25./* demonstrate > operator */

26.result = (x > y);

27.printf("bool result = (x > y);");

28.print_bool(result);

29. 

30./* demonstrate >= operator */

31.result = (x >= y);

32.printf("bool result = (x >= y);");

33.print_bool(result);

34. 

35./* demonstrate < operator */

36.result = (x < y);

37.printf("bool result = (x < y);");

38.print_bool(result);

39. 

40./* demonstrate <= operator */

41.result = (x <= y);

42.printf("bool result = (x <= y);");

43.print_bool(result);

44. 

45. 

46./* keep console screen until a key stroke */

47.char key;

48.scanf(&key);

49.}

Here is the output:

x = 10
y = 20
bool result = (x == y);false
bool result = (x != y);true
bool result = (x > y);false
bool result = (x >= y);false
bool result = (x < y);true
bool result = (x <= y);true
