你好，我想请问这个均匀有随机么？
#include
#include
const double PI = 3.14159265358979;
int main() {
FILE *outfp;
char filename[] = "sin.dat";
double alpha,delta = 360/20;
if((outfp = fopen(filename,"wt")) == NULL) {
printf("不能打开文件:%s\n",filename);
return 1;
}
for(alpha = 0; alpha <= 360; alpha += delta) {
printf("%4.0lf : %lf\n",alpha,sin(alpha * PI/180));
fprintf(outfp,"%.0lf %lf\n",alpha,sin(alpha * PI/180));
}
printf("\n");
return 0;
}
