1、ubuntu 14.04 linux cgcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2

2、#include<stdio.h>#include<stdlib.h>int main(){ char integer[100]; int value = 0,temp_value = 0,sum = 0; gets(integer); value = atoi(integer); temp_value = value; while(value >= 1) { sum += value%10; value = value / 10; } printf("the integer is %d and the sum of decimal digits is %d \n",temp_value,sum); return 0;}

3、xxx@linux:~/code$ gcc -o sum sum.cxxx@linux:~/code$ ./sum123the integer is 123 and the sum of decimal digits is 6xxx@linux:~/code$ ./sum12345the integer is 12345 and the sum of decimal digits is 15
