Question

C语言一维数组求和

#include "stdio.h" void main() { void NONO( int sum1,double sum2);//函数声明 double rea[10]={ 8.95,68.81,43.21,13.55,69.38,56.46,15.52,76.06,82.33,83.17 }; int sum1; double sum2; /***********begin***********/ /************end************/ printf("sum1=%d,sum2=%.2f\n",sum1,sum2); NONO(sum1,sum2); } void NONO( int sum1,double sum2) { FILE *f; f=fopen("E:\\homework\\19020211\\PROGOUT.DAT","w"); fprintf(f,"sum1=%d,sum2=%.2f\n",sum1,sum2); fclose(f); }

Answer 1

这很简单啊，在中间填for(int i=0;i<10;i++){sum1+=rea[i];sum2+=rea[i];}
