我正在编写一个程序，随机选择一个数组中的 30 个数字，然后对这些数字使用数学方程式，然后根据每个组对数字进行排序。除了将它们分类到每个选定的组时，我已经能够让一切正常工作。我做错了什么，我该如何解决。顺便说一句，我对编程很陌生，所以非常感谢任何帮助

请试试这个：

#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 Salespeople\n" );

  for ( i = 0; i < 30; i++ )
  {
    printf( "%d\n", 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( "%f\n", 100 + ( float ) sales[i] * 0.09 );    //Mathematical equation
//  }

// 让我们做点什么对于 ( i = 0; i < 30; i++ ) { printf("apply some calculation here to %d\n", 销售[i]); 销售额[i]=100 + (浮点数)销售额[i] * 0.09; //数学方程式 printf( "and it becomes %f\n", ( 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( "0-9 : %d\n", temp[0] );
    printf( "0-9 : %d\n", temp[1] );
    printf( "0-9 : %d\n", temp[2] );
    printf( "0-9 : %d\n", temp[3] );
    printf( "0-9 : %d\n", temp[4] );
    printf( "0-9 : %d\n", temp[5] );
    printf( "0-9 : %d\n", temp[6] );
    printf( "0-9 : %d\n", temp[7] );
    printf( "0-9 : %d\n", temp[8] );
    printf( ">>>00  : %d\n", temp[9] );
  return 0;
}
