Thread: C Stock Sorting Program Issue

Hey guys, I'm new here and just started C this year in college. Next year I'm going to work on c++.

To kick my first post of, I have a question. I receive an error message with Visual c++ 2008 Express in the savetext function. Look like this:


Here's the code:

Code:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
/////////////////
#define SIZE 2
/////////////////
struct Stock
{
    char name[10];
    int numShares;
    float buyShare,currPrice,fees;
    float initCost,currCost,profit;
};
/* Load the data from the keyboard and calculates 
the Initial Cost, Current Cost, and Profit 
for each stock via an array */


void load(struct Stock s[], int n) 
{
    int i;
    for(i=0;i<n;i++)
    {
        printf("Enter the Stock Name\n");
        printf(">");
        gets(s[i].name);
        printf("Enter the Number of Shares\n");
        printf(">");
        scanf("%d", &s[i].numShares);
        printf("Enter the Buying Price Per Share\n");
        printf(">");
        scanf("%f", &s[i].buyShare);
        printf("Enter the Current Price Per Share\n");
        printf(">");
        scanf("%f", &s[i].currPrice);
        printf("Enter the Yearly Fees\n");
        printf(">");
        scanf("%f", &s[i].fees);


        s[i].initCost = (float)s[i].numShares * s[i].buyShare;
        s[i].currCost = (float)s[i].numShares * s[i].currPrice;
        s[i].profit = s[i].currCost - s[i].initCost - s[i].fees;


        fflush(stdin);
    }
}
