【简答题】
查找n在数组a中最后一次出现的位置(数组首元素的位置为零)。
例如:如果a数组中的元素为:1,5,2,5,6,8,7,4,3,0,
当n=5时,程序的输出结果为:5 is No.3 。
当n=10时,程序的输出结果应为:10 not found !。
#includevoid main( )
{ int a[10]={1,5,2,5,6,8,7,4,3,0};
int i,k,n,f=0;
scanf(%d,
for(i=0;ii++)
/************found************/
if([填空1])
{ f=1;
/************found************/[填空2]
}
if(f)
printf(%d is No. %d\n, n,k);
else
printf( %d not found !\n
}
