急求急急急急急求，急求用C语言编写一个计算器程序，代码量为三百行左右！！！！！各位大神们，帮帮忙

Answer 1

#include<stdio.h>
#include<stdlib.h>
#include<iostream.h>
float add(float x,float y)
{
x=x+y;return x;
}
float sub(float x,float y)
{
x=x-y;return x;
}
float mul(float x,float y)
{
x=x*y;return x;
}
float div(float x,float y)
{x=x/y;return x;}
void print()
{ printf(" /********欢迎使用精益计算机 ********/\n");
printf(" /******输入模式a+-*/b*****/\n");
printf(" /******输入字符c清屏*****/\n");
printf("请输入数据:");
}
void main()
{char i;
float a,b,c,d;
print();
loop: cin>>a; //scanf("%f",&a);
while(1)
{cin>>i;if(i!='c')cin>>b;//scanf("%c%f",&i,&b);
{switch(i)
{ case '+':{c=add(a,b);a=c;printf("=%0.1f",c);}break;
case '-':{c=sub(a,b);a=c;printf("=%0.1f",c);}break;
case '*':c=mul(a,b);a=c;printf("=%0.1f",c);break;
case '/':c=div(a,b);a=c;printf("=%0.1f",c);break;
case 'c' : system("cls");print();goto loop;break;

}
}
}
}
