有4个整数a,b,c,d,由键盘输入，输出其中最大的数（用if语句做）

#include <iostream.h>
int main(void)
{
int n;
int i;
int *value;
int max;
printf( "Number Count: " );
scanf( "%d", &n );
value = new int[n];
for( i = 0; i < n; i ++ )
{
printf( "Input Number[%d]: ", i + 1 );
scanf( "%d", &value[i] );
if( i == 0 )
max = value[0];
else
{
if( value[i] > max )
max = value[i];
}
}
printf( "\r\nMaxValue = %d\r\n", max );
delete[] value;

printf( "\r\n\r\n\t\tPress any key to continue ...");
getchar();
getchar();
