C语言高手帮我
#include "stdio.h"
void main()
{int i,fac=1;
for(i=0;i<=5;i++)
{
//此处与你的程序位置相反,因为2的0次幂是1,fac=1,直接输出fac=1,
//然后fac=fac*2;下次输出的就是2的1次幂，
//该循环共执行6次，最后一次输出fac=32
printf("fac=%d
",fac);
fac=fac*2;
}
}
是不对的，你求得是2的1次幂到6次幂。
这样就行了。
#include "stdio.h"
void main()
{int i,fac=1;
clrscr();
for(i=0;i<=5;i++)
{
if(i)fac=fac*2;
printf("fac=%d\n",fac);}
}
你这里是执行了6次循环了，即0一次1一次···5一次总共六次应该把for()里面的条件改成i=0;i<5;i++这样才是5次
你这是六次了，循环条件是i=0;i<5;i++
