1. 程序分析:首先判断此数是否大于最后一个数,然后再考虑插入中间的数的情况,插入后
此元素之后的数,依次后移一个位置。
2.程序源代码:
main()
{
int a[11]={1,4,6,9,13,16,19,28,40,100};
int temp1,temp2,number,end,i,j;
printf("original array is:\n");
for(i=0;i<10;i++)
printf("%5d",a[i]);
printf("\n");
printf("insert a new number:");
scanf("%d",&number);
end=a[9];
if(number>end)
a[10]=number;
else
{for(i=0;i<10;i++)
{ if(a[i]>number)
{temp1=a[i];
a[i]=number;
for(j=i+1;j<11;j++)
{temp2=a[j];
a[j]=temp1;
temp1=temp2;
}
break;
}
}
}
for(i=0;i<11;i++)
printf("%6d",a[i]);
}
