the sequence point is at the ;
Anonymous
alternatively, what stops a full computation (value computation and side effects) of the left side, followed by the full computation (value computation and side effects) of the right side. (or right side first, left side second)
result is 13 in this case

in case of a well defined expression, you will be able to figure out the answer using the sequence point rules alone. there will be no ambiguity. (unspecified behaviour does not affect the end result)

I have pic and i need code in c++

#include<iostream>
using namespace std;
int main()
{
int num;
cin>>num ;
if (num<100)
{
cout<<"number is less than 100";
}
else
cout<<"number is greater than 100";
return 0;
}
shriman_deepak
what is wrong with this code
Captain
shriman_deepak
The code is right ?
shriman_deepak
#include<iostream>
using namespace std;
int main()
{
char alphabet [1]
cout<<"Enter an alphabet";
cin>>alphabet;
switch ( alphabet)
{
case a:
cout<<"Apple"<<alphabet<<endl;
break;
case b:
cout<<"Ball"<<alphabet<<endl;
break;
default:
cout<<"kuch nhi"<<alphabet<<endl;
break;
}
return 0;
shriman_deepak
please check this one
shriman_deepak
Sorry where ?

is it a good idea to link against a system tbd file and a non system library? eg root/systemLib.tbd sysroot/systemLib.(dylib/so/dll/lib/def/a)

this code is running fine on my ide but not on leetcode,
Anshul
anyone please look into this and help me find out where i have gone wrong
Pavel
this code is running fine on my ide but not on leetcode,
Hi, does leetcode say what it doesn't like about this code? Does it crash, or not compile, or time limit exceeded?
Anshul
Anshul
But I found out the problem. Actually leetcode doesn't work when we use a static variable
Anshul
I did the same code with using a reference variable and it worked
Hanz
Because you're assigning 0 to a in the if statement instead of comparing them
Hanz
And 0 is a false value
ThanuC
In the if statement you have to put double equation also..
Hanz
Because non zero numbers is equal to true
Hanz
No problem
Eturnus
in if condition use == instead of =
Eturnus
#include<stdio.h>
int main(){
int a=0,b=10;
if(a==0){
printf("true");
}
else{
printf("false");
}
return 0;
}

Can anyone help me
Kishan
Given a sequence of integers, I need to get the number of contiguous sequences such that (k) th element of sub-sequence is max of entire sequence:
inputs: testcases
n and k for each testcase
and n space separated integers
outpu:
number of possible sub-sequences
For that I wrote this code
int main()
{
int t;
cin>>t;
while(t--)
{
long long n, k, mi=0;
int max=INT_MIN, count=0;
cin>>n>>k;
long long arr[n];
for(long long i=0; i<n; i++)
{
cin>>arr[i];
if(max<arr[i])
{
max=arr[i];
mi=i;
}
}
if(mi>=k-1)
{
count+=n-mi;
}
cout<<count<<endl;
}
return 0;
}
And ran some testcases it works but when I submit this solution it gives wrong answer and I can't find out the problem so any help.......?

In case of char arrays in c++, why I can't do this to copy char arrays.
a=b;
Say a and b are two char arrays
Alex
Just copy links
Alex
a = *b
Alex
Or: char[] *a = *b;
Alex
char *a = b;
Mr.
In C++, all code in main function will run, but have some case the compiler will run the code out of it?
Vlad
Vlad
It has overloaded operator=
Vlad
In C++, all code in main function will run, but have some case the compiler will run the code out of it?
You mean executing code beyond function scope?
Mr.
Yes
Vlad
Only if you assign to a static variable
Vlad
And you've guessed it. All the code will be within a function
Vlad
Just being called before entering main
Mr.
Hmm, okey. So only in main the code will be executed, but some functions need to be declared before
Vlad
Hmm, okey. So only in main the code will be executed, but some functions need to be declared before
Your main function should know what signatures to call
Vlad
But you can only supply a header with what main would call
Vlad
It doesn't need to know about everything else
