6.16.10

注意17行for语句结尾的';'，因为多写了个分号，找了好几种方法调试C源码，最后还是在for语句中加printf语句才发现这个分号
1.语法不熟
2.调试手段不够丰富

这是调试时的写法

以下是我写的答案，注释为调试用；
// 6.16.10

include <stdio.h>

int main(void)
{

int upperlimit = 7;

int lowerlimit = 6;

int init;

int sum = 0;

printf("Enter lower and upper integer limits: ");

scanf("%d %d", &lowerlimit, &upperlimit);

// scanf("%d", &lowerlimit);

// printf("%d %d\n", lowerlimit, upperlimit);

while ( upperlimit > lowerlimit)

{
// upperlimit 是最大值，lowerlimit 是最小值
init = 0;
for (init = lowerlimit; init <= upperlimit; init++)
{
// printf("init is %d\n", init);
// printf("lowerlimit is %d\n", lowerlimit);
// printf("upperlimit is %d\n", upperlimit);
sum = sum + init * init;
// printf("sum is %d\n", sum);
}
printf("The sums of the squares from %d to %d is %d\n", lowerlimit * lowerlimit,
upperlimit * upperlimit, sum);
sum = 0;
printf("The next set of limits: ");
scanf("%d %d", &lowerlimit, &upperlimit);

}
printf("Done\n");
return 0;

}
