C语言这道题怎么做

这道题为难我了

Answer 1

用数组保存一下然后求和就完了么，为难啥
#define MAX_NUM 100
int num[MAX_NUM] = {0};
int i = 0;
do
{
scanf("%d", &num[i++]);
} while (getchar() != '\n');
int* array = new int[num[0]];
memcpy(array, num + 1, sizeof(int)*num[0]);
int sum = 0;
for (int j = 0; j < num[0]; ++j)
{
sum += array[j];
}
printf("sum = %d", sum);
{
sum += array[j];

}
printf("sum = %d", sum);
