First, we need to look at the Boolean type first. The C99 standard for the C language supports Boolean types, and the keyword is _bool, which is used to represent the logical value TRUE and false. the C language uses a value of 1 to indicate true and a value of 0 for false. So a Boolean type is actually an integer type.

Programs often use expressions that contain relational operators for branching and looping operations. We will learn specifically in the chapters of branching and looping.

The C language provides 6 relational operators, as follows:

Let's look at a simple example:

#include <stdio.h>  int main (void)  {       int5;       int 3 ;         /* based on the actual values of the variable A and variable B, write the correct relational operator in the middle of a and B, so that the     expression returns a value of 1 (in the C language, true)*/      printf (  "%d\n", a! = b)      ; return 0 ;  }
