1-8.输入一个四位数,编程求出它的各数位之和

一：#includevoidmain(){inta,i=0,sum=0;scanf("%d",&a);while(a){sum+=(a%10);//sum是个位数之和a/=10;i++;//i为位数}

/*1100x+11y=11(100x+y)=n^2,0

TWOEIGHTONESIX所以答案应该是2816

intm,n;scanf("%d",&m);n=(m/1000)*(m/1000)+(m/100%10)*(m/100%10)+(m/10%10)*(m/10%10)+(m%10)*(m%10);pr

#includeintmain(){intn,sum=0;printf("请输入一个整数：");scanf("%d",&n);while(n){sum=sum+n%10;n/=10;}printf("

倒数……你的意思应该是：四位数ABCD*9=DCBA吧……那么我就按照我的理解来做了由题意可得(1000a+100b+10c+d)*9=1000d+100c+10b+a若a>或=2,则该数一定变为5位

#includevoidmain(){intn,sum=0,digit=0;scanf("%d",&n);while(n!=0){sum+=n%10;digit++;n/=10;}printf("每位

作为字符串形式读入比用整形读入好处理,而且数的位数不受限制（整型有数值超界问题）#includevoidmain(){chars[80];//最长80位数字inti,L;printf("pleasei
