为什么程序中输入不了a，只能输入b。很简单的内容。
#include<stdio.h>int multifly(int x,int y);
void main()
{
int a,b,c,i;
printf("please enter the value of b:\n");
scanf("b=%d",&b);
printf("please enter the value of a:\n");
scanf("a=%d",&a);
if(b<=0&&a<=0)
{
printf("sorry!you are wrong!\n");
}
else{
for(i=1;i<=a;i++)
{
c=multifly(a,b)*c;
}
printf("c=%d\n",c);
}
}
int multifly(int x,int y)
{
long int z;
z=x*y;
retur
