c - 怪异的迪基文件

Question

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

void get_file(void);
float Max_Horizontal(int, int);
float Max_Verticle(int, int);
float Time(int,int);

int main(void)
{

    get_file();

    return (0);
}

void get_file(void)
{
    int i = 0;
    int A[8][2];
    char buf[1000];

    FILE*Fpointin =fopen("trajin.txt","r");
    FILE*Fpointout =fopen("trajout.txt","w");

    if (Fpointin == NULL)
        {
            printf ("File does not exist.\n");
        }
    else
        {
            fgets(buf,1000, Fpointin);
        }

    while ((fscanf(Fpointin,"%d %d",&A[i][0],&A[i][1])==2))
        {
            {i++;}
            fprintf(Fpointout, "%.2f\t %.2f\t %.2f\t %.2f\t %.2f \n", A[i][0],A[i][1], Max_Horizontal(A[i][0],A[i][1]), Max_Verticle(A[i][0],A[i][1]), Time(A[i][0],A[i][1]));
        }
        fclose(Fpointin);
        fclose(Fpointout);
}

float Max_Horizontal(iInTrajectoryAngle,fInVelocity)
{
    double fMaxRange = 0;

    fMaxRange = ((pow(fInVelocity,2)*sin((((iInTrajectoryAngle*M_PI)/180)* 2)))/9.81);

    return(fMaxRange);
}

float Max_Verticle(iInTrajectoryAngle,fInVelocity)
{
    double fMaxHeight = 0;

    fMaxHeight =  (pow(fInVelocity,2) * pow(sin(((iInTrajectoryAngle*M_PI)/180)),2) / (2*9.81));

    return (fMaxHeight);
}

float Time(iInTrajectoryAngle, fInVelocity)
{
    double fFlightTime = 0;

    fFlightTime = ((2 * fInVelocity * sin(((iInTrajectoryAngle*M_PI)/180))/9.81 ));

    return (fFlightTime);
}

大家好，我已经为其中一个自动化在线类(class)完成了这个简短的程序，但输出文件很奇怪，我似乎不明白为什么。当然，该网站并没有多大帮助，因为它无法真正指出如何帮助修复我的错误。输入文件是一个简单的 .txt 文件，如下所示

初始角度(度) 初始速度(米每秒)10 10020 12030 13040 14050 15060 16070 17080180

想通了!必须改变

fprintf(Fpointout, "%f\t %f\t\t %.2f\t %.2f\t %.2f\n", A[i][0],A[i][1], Max_Horizontal(A[i][0],A[i][1]), Max_Verticle(A[i][0],A[i][1]), Time(A[i][0],A[i][1]));

至

fprintf(Fpointout, "%d\t %d\t\t %.2f\t %.2f\t %.2f\n", A[i][0],A[i][1], Max_Horizontal(A[i][0],A[i][1]), Max_Verticle(A[i][0],A[i][1]), Time(A[i][0],A[i][1]));

注意类型的变化。
