Using cout to print binary version of int

  #include<iostream>
  #include<cstdio>
  using namespace std;

  char*  bits(int val){
  const int size=sizeof(int)*8;
  static char str[size+1];
  int i;
  int j;
  for(i =(sizeof(int)*8-1), j=0;i>=0 ;i--, j++){ 
    val & (1 << i)&&(str[j]='1')||(str[j]='0');
  }
  str[j]=0;
  return str;
 }
 int main(){
  cout<<bits(2345);
  putchar('\n');
  return 0;
 }
