Click to expand...


because in below statement,the compiler(parser) see...
a>b>c as ((a>b)>c)
so ,if a=15,b=10,c=5
a>b ==> true (returns 1)
now 1 > 5 (c) ==> false

Therefore , compiler returns false .The concept of left associativity .
 
the whole concept of your program is wrong, how can you compare values without getting an input from an user and claim it as true or false ? :facepalm:
If you get an input from an user, and ask for "true or false", that has some sense. If you get my point and agree with what i say, then this must be the program :

Code: 
#include<stdio.h> 
void main() 
{ 
int a,b,c; 
scanf(%d %d %d, &a, &b, &c);
if(a>b&&a>c)
printf("True"); 
else 
printf("False"); 
}

If its "greatest of 3 numbers, then the program would be :

Code: 
#include<stdio.h> 
void main() 
{ 
int a,b,c; 
scanf(%d %d %d, &a, &b, &c);
if(a>b&&a>c)
printf("A is Big"); 
else 
if(b>c)
printf("B is Big"); 
else
printf("C is Big");
}

any doubts ? feel free to reply :)
