Question

C语言的这条程序检查没错， 为什么运行起来出错呢？

main()
{
int sign=1;
float deno=2.0,sum=1.0,term;
while(deno<=100)
{
sign=-sign;
term=sign/deno;
sum=sum+term;
deno=deno+1;
}
printf("The sum is %f.\n",sum);
}
EngBoon 根据你说的还是错误啊！

Answer 1

应该是：
main()
{
int sign=1;
float deno=2.0,sum=1.0;
float term;
while(deno<=100)
{
sign=-sign;
term=1.0/deno;
sum=sum+term * sign;
/*deno=deno+1; */
deno++;
}
printf("The sum is %lf.\n",sum);
}
