我正在编写一个程序，它在一个数组中随机选择30个数字，然后对这些数字使用数学方程，然后按每组对数字进行排序。我已经能够让一切工作，除了当它涉及到将它们分类到每一个选择性组。我做错了什么，我该怎么补救。顺便说一句，我对编程非常陌生，所以任何帮助都非常感谢

请试试:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(  )
{
  int i;
  int sales[30];
  int arraySize = 0;
  int temp[10] = { 0 };
  for ( i = 0; i < 30; i++ )
  {
    sales[i] = ( rand(  ) % 15000 ) + 1;    //   between 0 and 15000
  }
  printf( "Gross Sales of all 30 Salespeoplen" );
  for ( i = 0; i < 30; i++ )
  {
    printf( "%dn", sales[i] ); //Displays Orginal List and Lists all values that were randomly selected
  }
  printf( "nWage based on Gross Sales    n" );    //Displays calculated wages with math equation

 // this does not do anything
//  for ( i = 0; i < 30; i++ )
//  {
//    printf( "%fn", 100 + ( float ) sales[i] * 0.09 );    //Mathematical equation
//  }

//让我们做点什么对于(I = 0;我& lt;30;我+ +){Printf("对%dn应用一些计算"，sales[i]);销售额[i]=100 +(浮动)销售额[i] * 0.09;//数学方程Printf("并且它变成%fn"， (float)sales[i]);}

  for ( i = 0; i < 30; i++ )
      {
          printf("n sorting sales %d == %d " , i , sales[i] );
    if ( sales[i] >= 1000 )
      temp[9]++;
    else if ( sales[i] >= 900 && sales[i]<=999)
      temp[8]++;
    else if ( sales[i] >= 800 && sales[i]<=899)
      temp[7]++;
    else if ( sales[i] >= 700 && sales[i]<=799)
      temp[6]++;
    else if ( sales[i] >= 600 && sales[i]<=699)
      temp[5]++;
    else if ( sales[i] >= 500 && sales[i]<=599)
      temp[4]++;
    else if ( sales[i] >= 400 && sales[i]<=499)
      temp[3]++;
    else if ( sales[i] >= 300 && sales[i]<=399)
      temp[2]++;
    else if ( sales[i] >= 200 && sales[i]<=299)
      temp[1]++;
    else
      temp[0]++;
}
    printf( "n" );
    printf( "$100-$199 : %dn", temp[0] );
    printf( "$200-$299 : %dn", temp[1] );
    printf( "$300-$399 : %dn", temp[2] );
    printf( "$400-$499 : %dn", temp[3] );
    printf( "$500-$599 : %dn", temp[4] );
    printf( "$600-$699 : %dn", temp[5] );
    printf( "$700-$799 : %dn", temp[6] );
    printf( "$800-$899 : %dn", temp[7] );
    printf( "$900-$999 : %dn", temp[8] );
    printf( ">>>$1000  : %dn", temp[9] );
  return 0;
