check if two variable not equal in C

  if (variable1 != variable2) 
  {
     printf ("variable1 is not equal to variable2\n");
  }

This code checks if two variables are not equal. First, it starts with an “if” statement. This statement checks if the first variable (variable1) is not equal to the second variable (variable2). If this condition is true, the code then prints a message to the console saying that the two variables are not equal. If the condition is false, then the code will not execute. This code can be used for various applications, such as detecting user errors or finding inconsistencies in data.
