Relational Operators in C Programming

C Language has a following relational operators. For example: Assume variable A holds 100 and variable B holds 200 then −

Operator	Description	Example
==	Equals to	(A == B) is not true.
!=	Not equal	(A != B) is true.
>	Greater than	(A > B) is not true.
<	Less than	(A < B) is true.
>=	Greater than or equals to	(A >= B) is not true.
<=	Less than or equals to	(A <= B) is true.

Example: Write a C Program to find the largest of two numbers.

#include < stdio.h > int main() {
  int a, b, big;
  a = 10;
  b = 20;
  if (a > b) // if condition is true move inside if-statement
  {
    big = a;
  } else {
    big = b;
  }
  printf("Biggest of the two number is = %d", big);
  return 0;
}

Output

  Biggest of the two number is =  20
