请用C++ 编写程序，计算结果保存在TXT

Posted 2023-03-13

程序是：
#include <stdio.h>
#include<math.h>
void main ()

float A,B,x,y,I;
printf ("enter A and B \n");
scanf("%f%f",&A,&B);
printf("波长是%f,相位差是%f",A,B);

for (x=-35.0;x<35;x=x+0.14)
for(y=-35.0;y<35;y=y+0.14)
if (x*x+y*y<1225)
I=A*A*sin(atan2(x, y))*sin(atan2(x,y))*B;
else
I=0.0;
printf("%f ",I);

printf("\n");


最好，显示500*500的矩形的！
程序可改动
我用的是VC ++编译，并且我需要复制过去就直接能编译的程序，因为我vc还不是很了解！
麻烦你了
编译时：
ompiling...
数据1.c
d:\vc98\include\eh.h(32) : fatal error C1189: #error : "eh.h is only for C++!"
执行 cl.exe 时出错.

数据1.obj - 1 error(s), 0 warning(s)

还有能不能将运行结果导入excle结果最好500*500显示！
若excle不显示500*500，可以修改x=x+0.14和 y=y+0.14，显示100*100的！

其他地方可以改！

楼上大哥,问题补充有误，担忧乘不上下面的只能用这个形式：呵呵

还有能不能将运行结果导入excle结果最好500*500显示！
若excle不显示500*500，可以修改x=x+0.14和 y=y+0.14，显示100*100的！

其他地方可以改

下层则是出现这种情况：

怎么修改。 参考技术A #include <iostream>
#include <cmath>
#include <fstream>
using namespace std;

int main()
ofstream fout("output.txt");
float A, B, x, y, l;
cout<<"enter A and B"<<endl;
cin>>A>>B;
cout<<"波长是"<<A<<"相位差是"<<B;
for(x=-35.0; x<35; x=x+0.14)
for(y=-35.0;y<35; y=y+0.14)
if(x*x+y*y<1225)
I=A*A*sin(atan2(x,y))*sin(atan2(x,y))*B;
else
I=0.0;
fout<<I<<"\t";

cout<<endl;
fout.close();
参考技术B #include <stdio.h>
#include<math.h>
void main ()

FILE * fp = NULL;
fp = fopen("result.txt","w");
double A,B,x,y,I;
printf ("enter A and B \n");
scanf("%lf%lf",&A,&B);
printf("波长是%lf,相位差是%lf",A,B);
for (x=-35.0;x<35;x=x+0.14)

for(y=-35.0;y<35;y=y+0.14)

if (x*x+y*y<1225)
I=A*A*sin(atan2(x, y))*sin(atan2(x,y))*B;
else
I=0.0;
fprintf(fp,"%lf ",I);

fprintf(fp,"\n");

fclose(fp);
