求兩個(gè)數(shù)的最大公約數(shù)：
#include<stdio.h>
int main(void)
{
int u,v,temp;
printf("Please type in two nonnegative integers.\n ");
scanf("%i%i",&u,&v);

while(v!=0)
{
temp=u%v;
u=v;
v=temp;
}
printf("Their greatest common divisor is %i\n",u);
return 0;
}
將一個(gè)數(shù)的數(shù)字的次序倒轉(zhuǎn)過(guò)來(lái)輸出
#include <stdio.h>

int main(void)
{
 int number,right_digit;
 printf("Enter your number.\n");

 scanf("%i",&number);
 while(number!=0)
 {
   right_digit=number%10;
   printf("%i",right_digit);
   number=number/10;
 }
 printf("\n");
 return 0;

}
求一個(gè)整數(shù)的各個(gè)位上數(shù)的和：
#include <stdio.h>

int main(void)
{
 int number,tmp,count=0,no;

 printf("Enter a int number: ");
     scanf("%i",&number); 
  no=number;
 while(number!=0)
 {
  tmp=number%10;
  count+=tmp;
     number=number/10;
 }
 printf("The count of %i is %i.\n",no,count);
 return 0;
}
