getting wrong answer plz help

Question

#include <iostream>
using namespace std;

int main()
{
int a=5 ,b=6 ,c=8;
if (a>(b>c)) {
if(b>(c>a)) {
cout << "b is greater";
}
else {
cout << "a is greater";
}
}
else {
if (c>(a>b)) {
cout << "c is greater";
}
else {
cout << "Something's wrong";
}
}

return 0;
}
//output says b is greater

Answer 1

if( >( > ))

Don't use these.

Inside the second bracket, it is seeing whether or not b is greater than c. It is not, so it evaluates to false (or 0), a is then greater than 0, so the if statement evalutates to true.

Again, the second bracket of the second if statement is checking whether or not c is greater than a, which is true (or 1), c is greater than 1, so the if statement evaluates to true, printing out that b is the greatest.

Answer 2

#include <iostream>
using namespace std;

int main()
{
int a=5 ,b=6 ,c=8;
if (a>b)
{
if(a>c)
{
cout << "a is greater";
}
else
{
cout << "c is greater";
}
}
else
{
if (b>c){
cout << "b is greater";
}
else {
cout << "c is greater";
}
}

return 0;
}
//output says c is greater

Answer 3

You are not using the right logical operators... When you use (a>(b>c)) the compiler first check if b>c, which in your code it's false and then checks if a>false which is true as false it's equal to 0 (zero)...
I suppose that you really meant "if both a and b are greather than c".. in order to do that you should use (a>c)&&(b>c)... && it's the logical and operator in C++
Hope it helped...

Answer 4

#include <iostream>
using namespace std;

int main()
{
int a=20,b=9,c=7;
if((a>b)&&(a>c))
{
cout<<"a is greater";
}
else if((b>c)&&(b>a))
{
cout<<"b is greater" ;
}
else
{
cout<<"c is greater" ;
}

return 0;
}
//same program with logical operator i did well didnt i???
