C :

# include<stdio.h>
int main()
  {
  int a,b,c;
  a=3;
  b=8;
  c=max(a,b);
  printf("%d\n",c);
  a=11;
  b=6;
  c=max(a,b);
  printf("%d\n",c);
  a=-3;
  b=2;
  c=max(a,b);
    printf("%d\n",c);
  return 0;
  }
int max(int x,int y)
  {
  int z;
  if(x>y)z=x;
  else z=y;
  return(z);
  }
    

C++ :

#include <stdio.h>
int main(int argc, char *argv[])
{
	int a,b;
	for(;scanf("%d%d",&a,&b)==2;)
		printf("%d\n",a>b?a:b);
	return 0;
}
