开始
声明变量k,m,i=2,a[n],s=0,m=999,n=1;
k=sqrt(m) m=m-2
是
m%i=0,
否
i=i+1
是 i<=k?
否
是 n<=10a[n]=m, n=n+1
?
否
n=1
s=s+a[n]
n=n+1
是
n<10?
否
输出
s=a[1]+a[2]+a[3]+a[4]+a[5]+a[6]+a[7]+
a[8]+a[9]+a[10]

7 出现问题及解决方法
(1)对c语言编程不熟练，导致编程很是困难，经过认真地学习课本的内容和做实验后编程有 所改善。
(2)实验的过程中会忘记声明变量，得认真地检查发现问题。
(3)判断素数的程序编写错误，在同学的帮忙下得以解决。
.8实验心得
(1) 通过实验我对c语言的编程语言更加熟悉，加快编程输入语言的速度。 (2) 对for语句格式及使用方法了解的清楚了点，掌握三种循环控制语句的循
环过程以及循环结构的嵌套，利用三种循环语句实现循环结构。 (3) 再次让我明白做实验时要细心，认真检查。
