When anything becomes zero its equal to false or else its true. In C there is nothing bool but everything is with respect to 0 and Non zero. 0 being false and Non Zero is true.

Say if you have something like if(1) will always be true.

1 #include<stdio.h>
2 void afunction(int *x)
3 {
4 x=new int;
5 *x=12;
6 }
7 int main()
8 {
9 int v=10;
10 afunction(&v);
11 printf("%d",v);
12 }

Error c:\lcc\test.c: 4 undeclared identifier 'new'
Error c:\lcc\test.c: 4 operands of = have illegal types 'pointer to int' and 'int'
Warning c:\lcc\test.c: 4 possible usage of new before definition

    *x=12;
}

{
    int v=10;
    afunction(&v);
    printf("%d",v);
	return 0;
}
