這個(gè)關(guān)鍵是怎么得到每位數(shù),
#include
int sum_num(int num)//得到每位數(shù)的函數(shù)
{
int sum=0;
while(num>10) //計(jì)算每位數(shù)的循環(huán),先得到的是各位然后依次類推
{
sum+=num%10;
num/=10; //為下一步計(jì)算準(zhǔn)備
}
return sum;
}
void main(){
int sum=0,num;
printf("請輸入你的數(shù):");
scanf("%d",&num); //接收輸入數(shù)
sum=sum_num(num); //函數(shù)調(diào)用
printf("%d\n",sum);//打印計(jì)算結(jié)果
