Required
What is the condition checking?
The above statement is an if conditional statement. Analysing the statement in bits:
if -> This represents the beginning of the conditional statement
fish -.> The variable that is being checked
> 400 -> The condition which the variable is being measured by.
So, the statement above is checking if the value of variable fish is greater than 400.
<em>If the condition is true, the instructions associated to that if statement will be executed.</em>

#include <stdio.h>
int g; // declaring g as global variable
int main()
{
printf("%d",g); //printing global variable
return 0;
}
<u>Output</u>
