If you need help solving this problem, mention your approach and ask specific questions. Please avoid sharing your code and asking the Community to figure out “what’s wrong”.
What is wrong?
A = int(input())
B = int(input())
print(A+B)
Looks like you figured it out on your own. 
WHATS WRONG?
#include<stdio.h>
int main()
{
int A,B;
scanf("%d",&A);
scanf("%d",&B);
printf("%d",A+B);
return 0;
}
This code is okay.
I checked your latest submission. You are getting “Compilation Error”. Please check what you are being told in the submission page. There will be a brief explanation of why your code is failing to compile.
It accepted the first case.but the 2nd case is not correct…hlp pls
#include<stdio.h>
int main()
{
int A,B,sum;
A=4;
B=5;
sum=A+B;
{printf("%d",sum);}
return 0;
}
The reason is explained in the submission page:
You need to read the values of A and B from input.
I am confused though. You were already doing it correctly in your previous code. Why did you change that?
#include <bits/stdc++.h>
using namespace std;
int main() {
unsigned long long ll2,ll1;
cin >> ll1;
cin >> ll2;
cout <<ll1+ll2 << endl;
return 0;
}
I got Wrong answer on 6th test case… help me out
Why use unsigned long long?
I have solved a Problem but that is just running for 2 minutes.
what is wrong ?
when I submit my coding…it shows that its running…but when I refresh the page… everytime I can only see complitation error…
what’s wrong??
It is because there are syntactical errors in your code. You need to make sure the code you have written is valid C code.
When you get Compilation Error, pay close attention to what is said in the submission page. It will tell you about the exact issues in your code.
I wrote this code and it is running in Python IDLE.
def add(a,b):
if a < 20000000 and b <20000000:
print(a+b)
else:
pass
a = int(input())
b = int(input())
add(a,b)
But it is showing runtime error. Why?
@amin2783
The numbers are in the same line not in separate lines.
try using,
a, b = map(int, input().split())
instead of
a = int(input())
b = int(input())
Got it, thanks @touhidur
#include <stdio.h>
int main() {
int a,b;
scanf("%d,%d",&a,&b);
printf("%d",a+b);
return 0;
}
What is wrong?
scanf("%d,%d",&a,&b);
