好的，所以我正在尝试编写一个程序来竞标汽车。我想要做的是，如果当前出价为零，那么最低出价就是起始出价。如果当前出价不为零，则最低出价是当前出价加上最低出价。我不断收到一条错误消息incompatible types when assigning to type 'float[5]' from type 'float'。
这是我的代码：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int menu1();
int main()
{
FILE * ifp = fopen("input2.txt","r"); //Open the input file
int cars = 5, i , j, k; // Initialized cars and counters i, j, and k
char *VIEW="VIEW", *BID="BID", *CLOSE="CLOSE", choice1[20]; //Initialize character arrays
float CAR[5]={1,2,3,4,5},START_BID[5]={0.00}, MIN_BID[5]={0.00}, CUR_BID[5]={0.00}, USR_BID[5]={0.00}; //Initialized float arrays
int compareLimit = 100, selection=0;
//Scan the file and appropriate the numbers into their respective arrays
for (i = 0; i < cars; i++)
{
fscanf(ifp, "%f %f", &START_BID[i],&MIN_BID[i]);
}
printf("Welcome to the Silent Auction\n\n");
menu1(); //Display the menu
while (selection < 3)
{
scanf("%s", choice1);
int result = strncmp(choice1, VIEW, compareLimit); //Compare two strings
if(result == 0)
{
selection = 1;
}
int result2 = strncmp(choice1, BID, compareLimit); //Compare two strings
if(result2 == 0)
{
selection = 2;
}
int result3 = strncmp(choice1, CLOSE, compareLimit); //Compare two strings
if(result3 == 0)
{
selection = 3;
}
if (selection == 1)
{
printf("Number\tCurrent Bid\tMinimum Increase\n");
printf("1\t$%.2f\t\t$%.2f\n",CUR_BID[0], MIN_BID[0]);
printf("2\t$%.2f\t\t$%.2f\n",CUR_BID[1], MIN_BID[1]);
printf("3\t$%.2f\t\t$%.2f\n",CUR_BID[2], MIN_BID[2]);
printf("4\t$%.2f\t\t$%.2f\n",CUR_BID[3], MIN_BID[3]);
printf("5\t$%.2f\t\t$%.2f\n",CUR_BID[4], MIN_BID[4]);
menu1();
}
else if (selection == 2)
{
int k;
float usr_bid;
printf("Which auction would you like to bid on? (1-5)\n");
scanf("%d", &k);
if (CUR_BID[k-1] != 0.00)
MIN_BID = CUR_BID[k-1] + MIN_BID[k-1];
else
printf("The minimum bid is %.2f\n", MIN_BID[k - 1]);
printf("How much would you like to bid?\n");
scanf("%f", &usr_bid);
if (usr_bid < MIN_BID[k-1])
printf("Sorry, that bid is not high enough.\n");
else
CUR_BID[k-1] = usr_bid + CUR_BID[k-1];
menu1();
}
else
{
int i;
for (i=0; i<cars; i++)
if (CUR_BID!=0)
printf("Auction %d sold for $%f\n", CAR[i],CUR_BID[i]);
else
printf("Auction %d did not sell.\n");
break;
}
}
fclose(ifp);
return 0;
}
int menu1()
{
printf("Please make a selection (In all caps):\n");
printf("\tView Auctions [VIEW]\n");
printf("\tBid on an Auction [BID]\n");
printf("\tClose Auctions [CLOSE]\n");
}
我的代码在该else if (selection == 2)部分中所做的是询问我要出价的出价。然后我从 1-5 中选择的任何数字都在 int k 中。然后它检查该选择的当前出价，因此它在CUR_BID[k-1]数组中查找，如果数字为 3，则检查数组中的第二个位置。我收到以下错误：
MIN_BID = CUR_BID[k-1] + MIN_BID[k-1];
有任何想法吗？
