1000 -- A + B Problem Time Limit :1000 MS Memory Limit :65536 KB Accepts : 1508 Submits : 2479 User Accepts : 1010 User Submits : 1060       Description Calculate A + B Input Two integer A B, 1 <= A, B <= 1000 Output A + B Sample Input 1 2 Sample Output 3 Hint Q: Where are the input and the output? A: Your program shall always read input from stdin (Standard Input) and write output to stdout (Standard Output). For example, you can use 'scanf' in C or 'cin' in C++ to read from stdin, and use 'printf' in C or 'cout' in C++ to write to stdout. You shall not output any extra data to standard output other than that required by the problem, otherwise you will get a "Wrong Answer". User programs are not allowed to open and read from/write to files. You will get a "Runtime Error" or a "Wrong Answer"if you try to do so. Here is a sample solution to problem 1000 using C++/G++:    ```#include using namespace std; int main() { int a,b; cin >> a >> b; cout << a+b << endl; return 0; } It's important that the return type of main() must be int when you use G++/GCC,or you may get compile error. Here is a sample solution to problem 1000 using C/GCC:``` ```#include int main(){ int a,b; scanf("%d %d",&a, &b); printf("%d ",a+b); return 0; } Here is a sample solution to problem 1000 using Java: Now java compiler is jdk 1.5, next is program for 1000 import java.io.*; import java.util.*; public class Main{ public static void main(String args[]) throws Exception { Scanner cin=new Scanner(System.in); int a=cin.nextInt(),b=cin.nextInt(); System.out.println(a+b); } } Here is a sample solution to problem 1000 using Pascal: program p1000(Input,Output); var a,b:Integer; begin Readln(a,b); Writeln(a+b); end.``` SourceClassical Problem
