编译通过，但是结果不准确!

收到!谢了，各位!

晕 你又定义了一个icome 然后又没赋初值 是做什么的

#include<stdio.h>

float single_tax(float income)
{
float tax;
if(income>=0&&income<=23350)
tax=income*0.15 ;
else if (23350<=income&&income<=56550)
tax=3502.50+(income-23350)*0.28;
else if(56550<=income&&income<=117950)
tax=12798.50+(income-56550)*0.31;
else if(117950<=income&&income<=256500)
tax=31832.50+(income-117950)*0.36;
else if(income>256500)
tax=81710.05 +(income-81710.05)*0.396;
return tax ;
}

main()
{
float i;
printf("input income:\n");
scanf("%f" ,&i);
single_tax(i) ;
printf("%f" , single_tax(i)) ;
getchar();
getchar();
}

VC6.0下通过

我晕,my god!谢谢楼上的!
