#include<stdio.h>  //中间的空格呢?
int printf(int n);  // 你要重写printf函数阿? 应该是print吧!
void main()
{
    int i,n;
    printf("\nPlease enter 1 integer:");
    scanf("%d",&n);
    i=printf(n);   //这里
    if(!i)printf("Error data!\n");
    printf("The value of print is %d!",i);
}
int print(int n)
{
    int i,j;
    if(n>=1&&n<=9)
    {
        for(i=1;i<=n;i++)
        {
            for(j=n-i;j>=1;j--)
                printf(" ");
            for(j=1;j<=2*i-1;j++)
                printf("%d",i);
            printf("\n");
        }
        return 1;

函数声明与调用处的函数名写错了.将printf改成print

谢了，我改下试试

谢了，看来大家都是高手啊，一眼就看出来了!!!
