回复:(lzmhstc)[求助]计算一个整数的各位数字之和的...
这个程序可以连续的计算好几个数字的所有位得所有数之和,并且因为使用了长整形,所以,可以计算的数字更大。
#include "math.h"
#include "stdio.h"
int f(long int n,int sum){
if(n/10==0)return sum+n;
return n%10+f(n/10,sum);
}
main()
{
long int n,sum=0;
printf("Please input the number to end with #:\n");
scanf("%ld",&n);
while(n)
{
printf("The all number add together is :\n");
printf("%d",f(n,sum));
printf("\n\nPlease input 1 to exit or other to continue:");
scanf("%ld",&n);
if(n==1)
{
printf("Please press to exit...");
getch();
exit(0);
}
printf("\nPlease input the number to end with #:\n");
scanf("%ld",&n);
}
getch();
}
