is 0 true or false
Is 0 true or false in the C programming language?
In the C programming language, the value 0 is considered false. This is because in C, any non-zero value is considered true. Therefore, 0 is the only value that is treated as false in conditional statements and boolean expressions.
This convention is based on the concept of "truthiness" in C, where any non-zero value is considered true and zero is considered false.
Here is an example to illustrate this:
#include <stdio.h>
int main() {
int value = 0;
if (value) {
printf("The value is true\n");
} else {
printf("The value is false\n");
}
return 0;
}
In this example, the condition if (value)
evaluates to false because value
is 0. Therefore, the program will print "The value is false" as the output.
